(show all your work)
1.) 5t = 4t + 3
2.) 4a + 3 = 3a + 5

2. Solve: 5t = 4t + 3
5t = 4t + 3
5t - 4t = 4t- 4t + 3
t = 3

3. 15 = 12 + 3 15 = 15 Check: 5t = 4t + 3 5(3) = 4(3) + 3 5t = 4t + 3
True

4. Solve: 4a + 3 = 3a + 5 a + 3 = 5 a + 3 -3 = 5 - 3 a = 2

5. 4(2) + 3= 3(2) + 5 8 + 3 = 6 + 5 11 = 11 Check: 4a + 3 = 3a + 5
True

1.) x = 27
2.) x = 30
3.) x - x = 12

10. Bellwork 10/7 Solve and Check
1.) x = 27
(3/1)x = 27(3/1)
x = 81
x = 27
(81) = 27
27 = 27
Check

2.) x = 30
(8/5) x = 30(8/5)
x = 48
x = 30
(48) = 30
30 = 30
Check

12. Bellwork 10/7 Solve and Check
3.) x - x = 12
4/8x = 12 or ½x = 12
(2/1)½x = 12(2/1)
x = 24
x - x = 12 (24) - (24) = = = 12

13. Today’s Objective
To use the 4 steps to solve algebraic equations with variables on both sides.

14. 3x + 16 = 2x - 5 Variable on Both sides 3x-2x + 16 = 2x-2x - 5

15. 2x - 6 = 3(2x + 10) Variable on Both sides 2x - 6 = 6x +30
2x-2x-6 = 6x-2x+30
-6 = 4x + 30
-6-30 = 4x

16. Variable on Both sides
-6-30 = 4x
-36 = 4x
-36/4 = 4x/4
-9 = x

17. 2x - 4 = 2(4x - 8) Now you try it 2x - 4 = 8x - 16 2x-2x-4 = 8x-2x-16

18. Now you try it
-4+16 = 6x
12 = 6x
12/6 = 6x/6
2 = x

19. Now you try it 4 -4 + x = -2 -4 4(1 - x) + 3x = -2(x + 1)

22. Bellwork 10/2 (1 of 2) 4 -4 + x = -2 -4 4(1 - x) + 3x = -2(x + 1)

23. Bellwork 10/2 (2 of 2) Follow the steps below to solve 6x = 42
1.) Multiply both sides by 1/6
(1/6)6x = 42(1/6)
x = 7
