3x%2B2%285x%2B20%29=170 Start with the given equation.


3x%2B10x%2B40=170 Distribute.


13x%2B40=170 Combine like terms on the left side.


13x=170-40 Subtract 40 from both sides.


13x=130 Combine like terms on the right side.


x=%28130%29%2F%2813%29 Divide both sides by 13 to isolate x.


x=10 Reduce.
