Work Step by Step

Add $\frac{3}{5}$ to both sides of the equation to isolate the variable. x-$\frac{3}{5}$=$\frac{7}{10}$ x=$\frac{7}{10}$+$\frac{3}{5}$ x=$\frac{7}{10}$+$\frac{6}{10}$ x=$\frac{13}{10}$ Check the answer. ($\frac{13}{10}$)-$\frac{3}{5}$=$\frac{7}{10}$ $\frac{13}{10}$-$\frac{6}{10}$=$\frac{7}{10}$ $\frac{7}{10}$=$\frac{7}{10}$
