What does this equal tox= -9a: -45 = 5xb: -7x = -63c: -11 = -2 -xd: 6x = 54

I'm guessing you mean which equation Equals -9

In each equation you are needing to get rid of X so you divide on both sides

A) -45=5x

-45/5=x
-9=x

and I double checked to make sure nothing else equaled -9 so Your answer Is A

Hope this helped!
