7%28x%2B4%29=9%28x-2%29 Start with the given equation.


7x%2B28=9x-18 Distribute.


7x=9x-18-28 Subtract 28 from both sides.


7x-9x=-18-28 Subtract 9x from both sides.


-2x=-18-28 Combine like terms on the left side.


-2x=-46 Combine like terms on the right side.


x=%28-46%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=23 Reduce.
