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

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

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

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

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

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

5. 3m – (5m – 2) = 4m + 2(m – 7)

A concert was held at RHS. The income from the concert came from a \$250 donation from the school and ticket sales at \$8 per ticket. Rent for the auditorium was \$200. The school had to pay the band \$1400, plus \$2 for each ticket sold. The school broke even (didn’t make or lose any \$). How many tickets were sold?

HW #1-12 Answers: 1.x = 12. x = 13. x = 7 4. x = 105. x = 56. x = 6 7.x = 128. x = -129. x = -2 10. x = 1111. x = 512. x = 3
