Question 698674
{{{-86-7x=79+4x}}} Start with the given equation.



{{{-7x=79+4x+86}}} Add {{{86}}} to both sides.



{{{-7x-4x=79+86}}} Subtract {{{4x}}} from both sides.



{{{-11x=79+86}}} Combine like terms on the left side.



{{{-11x=165}}} Combine like terms on the right side.



{{{x=(165)/(-11)}}} Divide both sides by {{{-11}}} to isolate {{{x}}}.



{{{x=-15}}} Reduce.
