-%284a-7%29-5a=10%2Ba Start with the given equation.


-4a%2B7-5a=10%2Ba Distribute.


-9a%2B7=10%2Ba Combine like terms on the left side.


-9a=10%2Ba-7 Subtract 7 from both sides.


-9a-a=10-7 Subtract a from both sides.


-10a=10-7 Combine like terms on the left side.


-10a=3 Combine like terms on the right side.


a=%283%29%2F%28-10%29 Divide both sides by -10 to isolate a.


a=-3%2F10 Reduce.
