x%2B38=3%28x%2B8%29 Start with the given equation.


x%2B38=3x%2B24 Distribute.


x=3x%2B24-38 Subtract 38 from both sides.


x-3x=24-38 Subtract 3x from both sides.


-2x=24-38 Combine like terms on the left side.


-2x=-14 Combine like terms on the right side.


x=%28-14%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=7 Reduce.
