Question 788444
{{{90+80+5x+4x+10=360}}} Start with the given equation.



{{{9x+180=360}}} Combine like terms on the left side.



{{{9x=360-180}}} Subtract {{{180}}} from both sides.



{{{9x=180}}} Combine like terms on the right side.



{{{x=(180)/(9)}}} Divide both sides by {{{9}}} to isolate {{{x}}}.



{{{x=20}}} Reduce.
