Answer:

1. 4(x -3) = 32

4x - 12 = 32

4x = 32 - 12

4x = 20

4x /4 = 20 /4

x = 5

2 . 12 ( 2x + 4 ) = 24

24x + 48 = 24

24x = 24 - 48

24x = - 24

Divide both sides by 24

x = - 1

3. 3 ( 3s + 4) = 24

9s + 12 = 24

9s = 24 - 12

9s = 12

9s = 12

Divide both sides by 9

s = 12 /9

4. 3 ( c - 2 ) = 2 ( c +3 )

3c - 6 = 2c + 6

3c - 2c = 6 + 6

c = 12

5 . 12(r - 3 )= 6 (r + 3)

12r - 36 = 6r + 18

12r - 6r = 18 + 36

6r = 54

Divide both sides by 6

r = 9

6 . 2 ( x + 5 ) = 30

2x + 10 = 30

2x = 30 - 10

2x = 20

x = 10
