1 Equations with variables on both sides Sections 3.11

2 Solving for the variable  GOAL: To get the variable by itself  Steps:  Get the variable on one side (try to keep it positive)  “ Undo” by performing the opposite operation  Follow the REVERSE of the order of operations

3 Examples: 1. 2x + 4 = 6x2. -5x + 3 = -12x 3. 6a = -2(a – 2)4. 5m – 18 = -4m

4 Examples: 5. -3x – 5 = 7x – 3 6. 2x + 2= 5(x – 2) 7. 7x – 8 = 7x - 58. 12 + 5c = -4c - 6

5 Classwork  Pg 157 # 4-11  Wkst 3.4 A # 1-9 together

6 Homework  Wkst 3.4 A # 10-18
