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:

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

Let me know if you need any clarification!
