Question

what is a ?
9a-3(a-6)=-6

Answer 1

You have to isolate a. Can you do that?

Answer 2

I've tried ton of numbers i can't find a

Answer 3

Ok. So you first have to distribute 3(a-6). What does that look like?

Answer 4

how would i do that you don't have to tell me the answer

Answer 5

So basically, you multiply each thing in the parenthesis.
So 3(a-6) would be,
3*a - 3*6. Does that make sense?

Answer 6

but i don't know what a is so how am i suppose to solve a problem that i don't know how to solve

Answer 7

I'm getting there. I'm helping you through it. Do you understand the distribution that I just did?

Answer 8

no.

Answer 9

You multiply the 3 with everything inside the parenthesis. So you get 3a - 18.

So your new equation will look like this,
9a-3a-18=-6. How do you simplify this?
