Question 133203


{{{7n+5=10n-10}}} Start with the given equation




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



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



{{{-3n=-10-5}}} Combine like terms on the left side



{{{-3n=-15}}} Combine like terms on the right side



{{{n=(-15)/(-3)}}} Divide both sides by -3 to isolate n




{{{n=5}}} Divide

Answer:

So our answer is {{{n=5}}}
