4) \frac{3m+15}{2} = 22.5

Multiply by 2 on both sides

3m + 15 = 45

Subtract both sides by 15

3m = 30

Divide both sides by 3

so m = 3

5) 21= \frac{q+35}{8}

Multiply both sides by 8

168 = q + 35

Subtract both sides by 35

q = 133

6) 14 + \frac{4z}{-11} = 66

Subtract 14 from both sides

\frac{4z}{-11} = 52

multiply by -11 on both sides

4x = 572

Divide both sides by 4

x= 143

7) \frac{3}{5} c - 6 = 9

Add 6 on both sides

\frac{3}{5} c  = 15

Multiply both sides by 5

3c = 75

Divide both sides by 3

c = 25

8) \frac{t}{-2} + 17 = -9

Subtract both sides by 17

\frac{t}{-2} =26

Multiply both sides by -2

t = -52

9) -6 = \frac{5p-(-2)}{-7}

Multiply both sides by -7

42= 5p + 2

subtract 2 from both sides

40 = 5p

Divide both sides by 5

so p = 8
