\frac{3}{5}u-\frac{9}{4}=-\frac{5}{3}
Swap sides so that all variable terms are on the left hand side.
\frac{3}{5}u=-\frac{5}{3}+\frac{9}{4}
Add \frac{9}{4} to both sides.
\frac{3}{5}u=-\frac{20}{12}+\frac{27}{12}
Least common multiple of 3 and 4 is 12. Convert -\frac{5}{3} and \frac{9}{4} to fractions with denominator 12.
\frac{3}{5}u=\frac{-20+27}{12}
Since -\frac{20}{12} and \frac{27}{12} have the same denominator, add them by adding their numerators.
\frac{3}{5}u=\frac{7}{12}
Add -20 and 27 to get 7.
u=\frac{7}{12}\times \frac{5}{3}
Multiply both sides by \frac{5}{3}, the reciprocal of \frac{3}{5}.
u=\frac{7\times 5}{12\times 3}
Multiply \frac{7}{12} times \frac{5}{3} by multiplying numerator times numerator and denominator times denominator.
u=\frac{35}{36}
Do the multiplications in the fraction \frac{7\times 5}{12\times 3}.
