## Algebra 1: Common Core (15th Edition)

$n=-2$
We start by creating a common denominator for all of the fractions: $\frac{2n}{10}-\frac{3n}{10}=\frac{2}{10}$ We now can combine the denominators on the same side of the equation: -$\frac{n}{10}=\frac{2}{10}$ We then multiply both sides by 10 to find: $-n=2$ We divide by -1 to obtain that $n=-2$. We plug -2 in for n and confirm that our answer is, indeed, correct.
