Answer 1

A) 5x - 4 = 2x + 8

5x - 2x = 8 + 4

3x = 12

x = 4

B) 6x + 9 = 2x + 25

6x - 2x = 25 - 9

4x = 16

x = 4

C) 8x + 24 = 4x + 44

8x - 4x = 44 - 24

4x = 20

x = 5

D) 9x - 16 = 5x + 32

9x - 5x = 32 + 16

4x = 48

x = 12

E) 2x - 16 = x + 20

2x - x = 20 + 16

x = 36

F) 3x + 24 = 2x - 32

3x - 2x = -32 -24

x = -56

G) 4x - 15 = 2x + 15

4x - 2x = 15 + 15

2x = 30

x = 15
