\frac{4}{5}y-\frac{5}{2}=-\frac{4}{3}
Swap sides so that all variable terms are on the left hand side.
\frac{4}{5}y=-\frac{4}{3}+\frac{5}{2}
Add \frac{5}{2} to both sides.
\frac{4}{5}y=-\frac{8}{6}+\frac{15}{6}
Least common multiple of 3 and 2 is 6. Convert -\frac{4}{3} and \frac{5}{2} to fractions with denominator 6.
\frac{4}{5}y=\frac{-8+15}{6}
Since -\frac{8}{6} and \frac{15}{6} have the same denominator, add them by adding their numerators.
\frac{4}{5}y=\frac{7}{6}
Add -8 and 15 to get 7.
y=\frac{7}{6}\times \frac{5}{4}
Multiply both sides by \frac{5}{4}, the reciprocal of \frac{4}{5}.
y=\frac{7\times 5}{6\times 4}
Multiply \frac{7}{6} times \frac{5}{4} by multiplying numerator times numerator and denominator times denominator.
y=\frac{35}{24}
Do the multiplications in the fraction \frac{7\times 5}{6\times 4}.
