y=\frac{3}{8}+\frac{4}{5}
Add \frac{4}{5} to both sides.
y=\frac{15}{40}+\frac{32}{40}
Least common multiple of 8 and 5 is 40. Convert \frac{3}{8} and \frac{4}{5} to fractions with denominator 40.
y=\frac{15+32}{40}
Since \frac{15}{40} and \frac{32}{40} have the same denominator, add them by adding their numerators.
y=\frac{47}{40}
Add 15 and 32 to get 47.
