-\frac{4}{3}v-\frac{3}{5}=\frac{1}{2}
Swap sides so that all variable terms are on the left hand side.
-\frac{4}{3}v=\frac{1}{2}+\frac{3}{5}
Add \frac{3}{5} to both sides.
-\frac{4}{3}v=\frac{5}{10}+\frac{6}{10}
Least common multiple of 2 and 5 is 10. Convert \frac{1}{2} and \frac{3}{5} to fractions with denominator 10.
-\frac{4}{3}v=\frac{5+6}{10}
Since \frac{5}{10} and \frac{6}{10} have the same denominator, add them by adding their numerators.
-\frac{4}{3}v=\frac{11}{10}
Add 5 and 6 to get 11.
v=\frac{11}{10}\left(-\frac{3}{4}\right)
Multiply both sides by -\frac{3}{4}, the reciprocal of -\frac{4}{3}.
v=\frac{11\left(-3\right)}{10\times 4}
Multiply \frac{11}{10} times -\frac{3}{4} by multiplying numerator times numerator and denominator times denominator.
v=\frac{-33}{40}
Do the multiplications in the fraction \frac{11\left(-3\right)}{10\times 4}.
v=-\frac{33}{40}
Fraction \frac{-33}{40} can be rewritten as -\frac{33}{40} by extracting the negative sign.
