-\frac{8}{3}y=-\frac{1}{2}-\frac{1}{6}
Combine -\frac{2}{3}y and -2y to get -\frac{8}{3}y.
-\frac{8}{3}y=-\frac{3}{6}-\frac{1}{6}
Least common multiple of 2 and 6 is 6. Convert -\frac{1}{2} and \frac{1}{6} to fractions with denominator 6.
-\frac{8}{3}y=\frac{-3-1}{6}
Since -\frac{3}{6} and \frac{1}{6} have the same denominator, subtract them by subtracting their numerators.
-\frac{8}{3}y=\frac{-4}{6}
Subtract 1 from -3 to get -4.
-\frac{8}{3}y=-\frac{2}{3}
Reduce the fraction \frac{-4}{6} to lowest terms by extracting and canceling out 2.
y=-\frac{2}{3}\left(-\frac{3}{8}\right)
Multiply both sides by -\frac{3}{8}, the reciprocal of -\frac{8}{3}.
y=\frac{-2\left(-3\right)}{3\times 8}
Multiply -\frac{2}{3} times -\frac{3}{8} by multiplying numerator times numerator and denominator times denominator.
y=\frac{6}{24}
Do the multiplications in the fraction \frac{-2\left(-3\right)}{3\times 8}.
y=\frac{1}{4}
Reduce the fraction \frac{6}{24} to lowest terms by extracting and canceling out 6.
