1 Formula Ratio Proportion Percent of change Weighted Average Equivalent Equations Solve an Equation Multistep Equations identify " And in the end it's not the years in your life that count. It's the life in your years." Abraham Lincoln

2 Objective: Solve equations with more that one operation. CFU ; Solve multi-step linear equations with one variable. CLE ; Solve problems involving linear equations and linear inequalities. SPI Write and/or solve linear equations, inequalities, and compound inequalities including those containing absolute value.

4 15 = = = 18 m – 48 = q = d = m = q = m = -45

5 Multiply by 5 k = 50 k = 10 5 k = * *5 k = *5* *5 Multiply by 3 a = 18 a = 6 3 a = 6 3 3* *3 a = 6 3 3*3* *3 Multiply by 11 x = 44 x = 4 11 x = * *11 x = * *11

6 25m = 100 Opposite Divide by 25 25m = m = m = 4 5n = 35 Opposite Divide by 5 5n = n = 35 5 n = 7 4p = 24 Opposite Divide by 4 4p = p= 24 4 p = 6

7 Multiply by 30

8 Opposite of multiplying by fraction is multiplying by its inverse! ½ B = 42 ¾ D = 12

9 Turn to page 81 and 82 Working with your partner complete the activities Turn to page 90 Working with your partner complete the activities As you work out each problem with the tiles, write your steps out algebraically on a paper to turn in

10 x + 4 = x = 21 x – 2 = -11 y–(- 12.1) = x = 1.9

11 7m – 17 = 60 subtracting add 17 7m = 77 multiplying by divide by 7 m = 11 check by substituting solution for variable 7(11) – 17 = – 17 = = 60 Start at last step farthest from variable - Open box before unfold

12 5q - 13 = 37 subtracting add 13 5q = 50 multiplying by divide by 5 q = 10 check by substituting solution for variable 5(10) – 13 = – 13 = = 37 Start at last step farthest from variable - Open box before unfold

13 Adding 21 Subtract 21 Dividing by 8 Multiply by 8 Check Start at last step farthest from variable - Open box before unfold

14 Subtracting 9 Add 9 Dividing by 12 Multiply by 12 Check Start at last step farthest from variable - Open box before unfold

15 Multiply by 9 Add 15

16 Check your solution
