Objective: Solve equations with more that one operation. CFU 3102.3.11; Solve multi-step linear equations with one variable. CLE 3102.3.4; Solve problems involving linear equations and linear inequalities. SPI 3102.3.5 Write and/or solve linear equations, inequalities, and compound inequalities including those containing absolute value.

15 = 15 15 + 3 = 15 18 = 18 m – 48 = 29 + 3 21 + q = -18142 + d = 97 + 48 +48 m = 77 -21 q = -39 -142 m = -45

Multiply by 5 k = 50 k = 10 5 k = 10 5 5* *5 k = 10 5 5*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 = 4 11 11* *11 x = 4 11 11* *11

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

Multiply by 30

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

x + 4 = -9-7 + x = 21 x – 2 = -11 y–(- 12.1) = - 2.3 7 + x = 1.9

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

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