v=-\frac{1}{4}+\frac{3}{8}
Add \frac{3}{8} to both sides.
v=-\frac{2}{8}+\frac{3}{8}
Least common multiple of 4 and 8 is 8. Convert -\frac{1}{4} and \frac{3}{8} to fractions with denominator 8.
v=\frac{-2+3}{8}
Since -\frac{2}{8} and \frac{3}{8} have the same denominator, add them by adding their numerators.
v=\frac{1}{8}
Add -2 and 3 to get 1.
