Question

-2(3a-b)=c , what would you do if you were trying to isolate b

Answer 1

`b=3a+(c)/(2)`

Explanation:

First, distribute the -2 to the rest of the parenthesis, following PEMDAS.

`-2(3a-b)=c\\-6a+2b=c`

Then, add -6a to both sides.

`2b = 6a+c`

Now, you can divide both sides by 2 to isolate b.

`b=(6a+c)/(2)`

Divide to simplify.

`b=3a+(c)/(2)`
