Question 387247
{{{5(20-x)+10x=165}}} Start with the given equation.



{{{100-5x+10x=165}}} Distribute.



{{{5x+100=165}}} Combine like terms on the left side.



{{{5x=165-100}}} Subtract {{{100}}} from both sides.



{{{5x=65}}} Combine like terms on the right side.



{{{x=(65)/(5)}}} Divide both sides by {{{5}}} to isolate {{{x}}}.



{{{x=13}}} Reduce.

Answer:


So the solution is {{{x=13}}}
