Answer:

See below.

Step-by-step explanation:

1) 4x + 8 = 2x + 10

2x = 2

x = 1

2) 9y - 3 = 6y + 12

3y = 15

y = 5

3) 8m + 4 =  4m - 20

4m = -24

m = -6

4) 11z - 14 = 5z + 4

6z = 18

z = 3

5) 3q - 6 = 8q - 6

5q = 0

q = 0  

6) 20n + 7 = 6n - 21

14n = -28

n = -2  

7) 2w - 8 = 7w - 3

5w = -5

w = -1

8) 9k + 4 = k - 12

8k = -16

k = -2
