Question

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

Answer 1

Answer:

$b=3a+\frac{c}{2}$

Step-by-step 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.

$b=\frac{6a+c}{2}$

Divide to simplify.

$b=3a+\frac{c}{2}$
