Solve:

3x + 7 = -8

• x = 5

• x = - 5

• x = -1/3 or -0.333

• x = 45

Solve:

-4x = 24

• x = 28

• x = 20

• x = 6

• x = - 6

Solve for y: 
2y + 7 = 11

• y = 2
• y = 1
• y = 9
• y = 4

Solve for h:

 $\frac{h}{4}+9=11$  

• h = 8

• h = 2

• h = 2/4 or 0.5

• h = 5

Solve for t.

14 = t + 7

• t = 2

• t = 6

• t = 7

• t = 21
