Solve the following equations. Match the equation with the correct solution.

• x=12

• 1/5x = 4

• x=9

• x + 14 = 5

• x=20

• 8x = 72

• x=-16

• x/-2=8

• x= -9

• -5 + x = 7

Solve for x.    -16+ x= -15

• 2

• 0

• -1

• 1

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

Solve:
7w + 5 = 3w - 15
