3x%2B9=7x%2B25 Start with the given equation.


3x=7x%2B25-9 Subtract 9 from both sides.


3x-7x=25-9 Subtract 7x from both sides.


-4x=25-9 Combine like terms on the left side.


-4x=16 Combine like terms on the right side.


x=%2816%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=-4 Reduce.
