Question 912621
{{{180-x=10+2(90-x)}}} Start with the given equation.



{{{180-x=10+180-2x}}} Distribute.



{{{180-x=190-2x}}} Combine like terms on the right side.



{{{-x=190-2x-180}}} Subtract {{{180}}} from both sides.



{{{-x+2x=190-180}}} Add {{{2x}}} to both sides.



{{{x=190-180}}} Combine like terms on the left side.



{{{x=10}}} Combine like terms on the right side.
