Answer 1

`9x - 7 = - 52`

Firstly rearrange the variable on the left side of the equation...

`9x = - 52 + 7`

Calculate the sum or differences

`9x = - 45`

`x = - (45)/(9) \\`

`x = - 5`

Answer 2

x = -5

Explanation:

9x - 7 = -52

we want to single out x,

add 7 to both sides to be one step closer to getting x alone

9x - 7 + 7 = -52 + 7

9x = -45

divided both sides by 9 to get x alone

9x / 9 = -45 / 9

x = -5
