y=\frac{3}{4}+\frac{2}{5}
Add \frac{2}{5} to both sides.
y=\frac{15}{20}+\frac{8}{20}
Least common multiple of 4 and 5 is 20. Convert \frac{3}{4} and \frac{2}{5} to fractions with denominator 20.
y=\frac{15+8}{20}
Since \frac{15}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.
y=\frac{23}{20}
Add 15 and 8 to get 23.
