Answer
r=-$\frac{13}{10}$
Work Step by Step
Subtract $\frac{3}{5}$ from both sides of the equation to isolate the variable.
r+$\frac{3}{5}$=-$\frac{7}{10}$
r=-$\frac{7}{10}$-$\frac{3}{5}$
r=-$\frac{7}{10}$-$\frac{6}{10}$
r=-$\frac{13}{10}$
Check the answer.
(-$\frac{13}{10}$)+$\frac{3}{5}$=-$\frac{7}{10}$
-$\frac{13}{10}$+$\frac{6}{10}$=-$\frac{7}{10}$
-$\frac{7}{10}$=-$\frac{7}{10}$
