2 STAIR Project by Katlyn Witt Click on the arrow to advance to the next page

3 Just like the title states, this STAIR will teach you how to solve multi-step equations. You can navigate through this presentation using the buttons at the bottom of the screen. The arrow buttons will take you back and forth between the different pages. The video camera button will take you back to the video mini-lesson, in the event you want to review or brush up on your skills.

4  Use the distributive property to simplify an equation.  Use the addition, subtraction, multiplication, and division properties of equality to solve an equation.  A1.2.1  A1.2.3

5 Click the video to play.

6 Using the steps you learned in the video, solve the following equations. You will want to have a writing utensil, paper, and a calculator (but it’s not necessary). Choose the best answer for each of the equations. Advance to the next page to begin.

7 2x + 10 = 6 x = - 2 I don’t know where to start I don’t know where to start x = ½ x = 8

8 You got the problem correct! Click the arrow in the corner to go to the next question.

9 2x and 10 are not considered like terms. Try again! Back to Question

10 It looks like you added 10 instead of subtracting it. Try again! Back to Question

11 The first thing you need to do is use the subtraction property of equality. Back to Question

12 Click the video to play. Back to Question

13 13 – 4x = -15 x = I don’t know where to start I don’t know where to start x = 7 x = ½

14 You got the problem correct! Click the arrow in the corner to go to the next question.

15 13 and -4x are not “like terms”. Try again! Back to Question

16 It looks like you added 13 instead of subtracting it from both sides. Try again! Back to Question

17 The 13 in front is positive, so you need to use the subtraction property of equality. Back to Question

18 Click the video to play. Back to Question

19 ½ x + 5 = 25 x = 40 I don’t know where to start I don’t know where to start x = 60 x = 45

20 You got the problem correct! Click the arrow in the corner to go to the next question.

21 It looks like you added 5 to both sides instead of subtracting 5. Try again! Back to Question

22 When getting rid of a fraction, you need to multiply everything by 2. You forgot to multiply the middle term as well. Try again! Back to Question

23 Start by using the subtraction property of equality to move the 5 to the other side. Back to Question

24 Click the video to play. Back to Question

25 3x – 4 + 5x = 12 x = - 8 I don’t know where to start I don’t know where to start x = 2 x = 1

26 You got the problem correct! Click the arrow in the corner to go to the next question.

27 Be careful with combining like terms. 3x + 5x is not -2x. Try again! Back to Question

28 It looks like you subtracted 4 from both sides instead of adding 4. Try again! Back to Question

29 Start by combining like terms on the left side. Back to Question

30 Click the video to play. Back to Question

31 12x + 10 = 3x + 55 x = 4.3 I don’t know where to start I don’t know where to start x = 2.6 x = 5

32 You got the problem correct! Click the arrow in the corner to go to the next question.

33 It looks like you added on both sides instead of subtracting. Try again! Back to Question

34 You can’t combine the x’s and the constants (just the numbers). Try again! Back to Question

35 Start with the subtraction property of equality. Back to Question

36 Click the video to play. Back to Question

37 4x + 5 – 2x = x x = - 5 I don’t know where to start I don’t know where to start x = 1.67 x = - 15

38 You got the problem correct! Click the arrow in the corner to go to the next question.

39 It looks like you combined like terms incorrectly. 4x – 2x is not 6x. Try again! Back to Question

40 It looks like you added 5 to both sides instead of subtracting 5. Try again! Back to Question

41 You need to combine like terms on the left first. Back to Question

42 Click the video to play. Back to Question

43 4(x – 6) = 16 x = 5.5 I don’t know where to start I don’t know where to start x = 0.67 x = 10

44 You got the problem correct! Click the arrow in the corner to go to the next question.

45 When distributing the 4, make sure you also multiply 4 times - 6. Try again! Back to Question

46 You cannot combine the -6 and the x inside the parenthesis. Try again! Back to Question

47 Distribute the 4 by multiplying it into the parenthesis. Back to Question

48 Click the video to play. Back to Question

49 7(x + 3) = x - 4 x = -0.2 I don’t know where to start I don’t know where to start x = 2.1 x = - 4

50 You got the problem correct! Click the arrow in the corner to go to the next question.

51 You cannot combine the x and the 3. Try again! Back to Question

52 It looks like you added 21 to both sides instead of subtracting it. Try again! Back to Question

53 Distribute the 7 by multiplying it into the parenthesis. Back to Question

54 Click the video to play. Back to Question

55 5(3 + 2x) = 35 x = 2 I don’t know where to start I don’t know where to start x = 10 x = 13.5

56 You got the problem correct! Click the arrow in the corner to go to the next question.

57 You need to be sure to distribute the 5 to both terms in the parenthesis. Try again! Back to Question

58 It looks like you subtracted the 5 that was in front of the parenthesis instead of distributing it. Back to Question

59 Distribute the 5 by multiplying it into the parenthesis. Back to Question

60 Click the video to play. Back to Question

61 10(7x – 6) = 30x + 20 x = -1 I don’t know where to start I don’t know where to start x = 1 x = 2

62 You got the problem correct! Click the arrow in the corner to finish the STAIR.

63 You cannot combine the 7x and -6. Try again! Back to Question

64 You cannot combine the 30x and the 20. Try again! Back to Question

65 Distribute the 10 by multiplying it into the parentheses. Back to Question
