Question

Z=9a-9-3b solve for a

Answer 1

So to solve for a, we must first get a on one side by itself. So let's add 9 to both sides to get:

`Z+9=9a-3b`

Then we are going to add 3b to both sides to get the a term by itself:

`Z+9+3b=9a`

And then since a has a coefficient of 9, we are going to divide by 9 to complete the solving for a:

`((Z+9+3b)/(9))=a`
