Question 611381
{{{-7x+5=21-5x}}} Start with the given equation.



{{{-7x=21-5x-5}}} Subtract {{{5}}} from both sides.



{{{-7x+5x=21-5}}} Add {{{5x}}} to both sides.



{{{-2x=21-5}}} Combine like terms on the left side.



{{{-2x=16}}} Combine like terms on the right side.



{{{x=(16)/(-2)}}} Divide both sides by {{{-2}}} to isolate {{{x}}}.



{{{x=-8}}} Reduce.
