Question

C) -7 - 6 = 5x + 2
D) x + 8 = 54 - x
E) - x - 4 = 11 + 2x

Answer 1

C) - 7 - 6 = 5x + 2

- 7 - 6 - 2 = 5x

- 15 = 5x

5x = - 15

x = - 15/5

x = - 3

~~~

D) x + 8 = 54 - x

x + x = 54 - 8

2x = 46

x = 46/2

x = 23

~~~

E) - x - 4 = 11 + 2x

- x - 2x = 11 + 4

- 3x = 15

x = 15/-3

x = - 5
