Question

-3x + -15 = 12
x = __

Answer 1

x=9

Explanation:

alright so first we eliminate the -15 and to do that we add 15 on both sides:

-3x-15+15=12+15

-3x=27

Now we divide 3 on both sides to make the equation equal to x

`(-3x)/(-3) = (27)/(-3)`

x=9

And that's your answer, you're welcome :)
