n = $-\frac{1}{4}$

Work Step by Step

$\frac{7}{5}n + \frac{3}{5} = -n$ Add n to both sides: $\frac{12}{5}n + \frac{3}{5}$ = 0 Subtract $\frac{3}{5}$ from both sides: $\frac{12}{5}n = -\frac{3}{5}$ Multiply both sides by the reciprocal of the coefficient: $\frac{5}{12}(\frac{12}{5}n) = -\frac{3}{5}(\frac{5}{12})$ n = $-\frac{1}{4}$
