Solve for p:

6p - 5 =13

• p = 12

• p = 15

• p = 3

• p = -3

Solve for x:

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

Simplify by distributing:

8(x + 5)

• 8x + 13

• 8x + 5

• 8x + 40

• 13x

Simplify by distributing:

3(2y - 7)

• 6y - 7

• 6y - 21

• 5y - 7

• 5y - 21

Simplify the equation, then solve for x:

2(2x - 1) = 10

• x = 3

• x = 2

• x = 6

• x = 2.25
