7%2B4a=8%28a%2B4%29 Start with the given equation.


7%2B4a=8a%2B32 Distribute.


4a=8a%2B32-7 Subtract 7 from both sides.


4a-8a=32-7 Subtract 8a from both sides.


-4a=32-7 Combine like terms on the left side.


-4a=25 Combine like terms on the right side.


a=%2825%29%2F%28-4%29 Divide both sides by -4 to isolate a.


a=-25%2F4 Reduce.
