P.O.D. Solve: 1. -3x + 7 = -112.

2
Solving: ax + b = cx + d # # # #

3
We must get the variables together before solving!! 5w + 1 = 2w + 13

4
Examples: 1. x + 50 = 2x + 100 2. 9n + 5 = 4n – 35

5
3. 3(2x + 4) = 2(2x + 25)

6
4. 12y + -9(y + 5) = 8(y – 1) – 2 + 2y

7
5. 3m – (5m – 2) = 4m + 2(m – 7)
