Question 219169


{{{7-2n=n-14}}} Start with the given equation.



{{{-2n=n-14-7}}} Subtract {{{7}}} from both sides.



{{{-2n-n=-14-7}}} Subtract {{{n}}} from both sides.



{{{-3n=-14-7}}} Combine like terms on the left side.



{{{-3n=-21}}} Combine like terms on the right side.



{{{n=(-21)/(-3)}}} Divide both sides by {{{-3}}} to isolate {{{n}}}.



{{{n=7}}} Reduce.
