7a-8%2B8-19=4a%2B19 Start with the given equation.


7a-19=4a%2B19 Combine like terms on the left side.


7a=4a%2B19%2B19 Add 19 to both sides.


7a-4a=19%2B19 Subtract 4a from both sides.


3a=19%2B19 Combine like terms on the left side.


3a=38 Combine like terms on the right side.


a=%2838%29%2F%283%29 Divide both sides by 3 to isolate a.
