5%28x-2%29%2B4%283%2Bx%29=20 Start with the given equation.


5x-10%2B12%2B4x=20 Distribute.


9x%2B2=20 Combine like terms on the left side.


9x=20-2 Subtract 2 from both sides.


9x=18 Combine like terms on the right side.


x=%2818%29%2F%289%29 Divide both sides by 9 to isolate x.


x=2 Reduce.
