Question 690150
{{{3x+2(5x+20)=170}}} Start with the given equation.



{{{3x+10x+40=170}}} Distribute.



{{{13x+40=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=(130)/(13)}}} Divide both sides by {{{13}}} to isolate {{{x}}}.



{{{x=10}}} Reduce.
