Question 352179


{{{5x+15=10(x-3)}}} Start with the given equation.



{{{5x+15=10x-30}}} Distribute.



{{{5x=10x-30-15}}} Subtract {{{15}}} from both sides.



{{{5x-10x=-30-15}}} Subtract {{{10x}}} from both sides.



{{{-5x=-30-15}}} Combine like terms on the left side.



{{{-5x=-45}}} Combine like terms on the right side.



{{{x=(-45)/(-5)}}} Divide both sides by {{{-5}}} to isolate {{{x}}}.



{{{x=9}}} Reduce.
