We start by using the distributive property to expand the terms 
and 
. When we do, we obtain 
and 
.
Putting those back into our equation, we have:
Next, we combine all of the constants on either side:
Finally, we want to get the variable a by itself on one side of the equation, so we perform the following steps to isolate it:
(Add 20 to both sides)
(Subtract 3a from both sides)
(Divide both sides by 2 to isolate a)
So, we obtain our answer of
.
