3y=\frac{7}{10}+2
Add 2 to both sides.
3y=\frac{7}{10}+\frac{20}{10}
Convert 2 to fraction \frac{20}{10}.
3y=\frac{7+20}{10}
Since \frac{7}{10} and \frac{20}{10} have the same denominator, add them by adding their numerators.
3y=\frac{27}{10}
Add 7 and 20 to get 27.
y=\frac{\frac{27}{10}}{3}
Divide both sides by 3.
y=\frac{27}{10\times 3}
Express \frac{\frac{27}{10}}{3} as a single fraction.
y=\frac{27}{30}
Multiply 10 and 3 to get 30.
y=\frac{9}{10}
Reduce the fraction \frac{27}{30} to lowest terms by extracting and canceling out 3.
