v=-\frac{1}{3}+\frac{4}{5}
Add \frac{4}{5} to both sides.
v=-\frac{5}{15}+\frac{12}{15}
Least common multiple of 3 and 5 is 15. Convert -\frac{1}{3} and \frac{4}{5} to fractions with denominator 15.
v=\frac{-5+12}{15}
Since -\frac{5}{15} and \frac{12}{15} have the same denominator, add them by adding their numerators.
v=\frac{7}{15}
Add -5 and 12 to get 7.
