Write the problem as a mathematical expression.

$3f+5g=-5$

$6f+5g=7$

Solve for $f$ in $3f+5g=-5$.

$f=-\frac{5}{3}-\frac{5g}{3}$

$6f+5g=7$

Replace all occurrences of $f$ with $-\frac{5}{3}-\frac{5g}{3}$ in each equation.

$-10-5g=7$

$f=-\frac{5}{3}-\frac{5g}{3}$

Solve for $g$ in $-10-5g=7$.

$g=-\frac{17}{5}$

$f=-\frac{5}{3}-\frac{5g}{3}$

Replace all occurrences of $g$ with $-\frac{17}{5}$ in each equation.

$f=4$

$g=-\frac{17}{5}$

List all of the solutions.

$f=4,g=-\frac{17}{5}$
