Question 188196


{{{7-4(3x+4)=-9x}}} Start with the given equation.



{{{7-12x-16=-9x}}} Distribute.



{{{-12x-9=-9x}}} Combine like terms on the left side.



{{{-12x=-9x+9}}} Add {{{9}}} to both sides.



{{{-12x+9x=9}}} Add {{{9x}}} to both sides.



{{{-3x=9}}} Combine like terms on the left side.



{{{x=(9)/(-3)}}} Divide both sides by {{{-3}}} to isolate {{{x}}}.



{{{x=-3}}} Reduce.
