Solve for x: 9x - 3 = -39 a -6 b -4 c 9 d 5

9x - 3 = -39
9x = -39 + 3
9x = -36
x = -36/9
x = -4

b -4

Hi there.

9x - 3 = -39

First, we need to isolate our variable. To do this, we have to add 3 to both sides as we are subtracting 3 from 9x, and adding 3 cancels it out.

-3 + 3 = 0
-39 + 3 = -36

We now have:
9x = -36

All we have to do now is divide both sides by 9 as we have 9 multiplying our variable, and as we previously mentioned, performing the opposite order of operations cancels the other out.

9x / 9 = x
-36 / 9 = -4

We have our solution:
x = -4

I hope this helps!
