Question 687257
{{{2n-7=5n-10}}} Start with the given equation.



{{{2n=5n-10+7}}} Add {{{7}}} to both sides.



{{{2n-5n=-10+7}}} Subtract {{{5n}}} from both sides.



{{{-3n=-10+7}}} Combine like terms on the left side.



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



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



{{{n=1}}} Reduce.
