\frac{1}{8}\times 3y+\frac{1}{8}\times 2=\frac{1}{4}\left(2y+\frac{1}{2}\right)+\frac{1}{2}
Use the distributive property to multiply \frac{1}{8} by 3y+2.
\frac{3}{8}y+\frac{1}{8}\times 2=\frac{1}{4}\left(2y+\frac{1}{2}\right)+\frac{1}{2}
Multiply \frac{1}{8} and 3 to get \frac{3}{8}.
\frac{3}{8}y+\frac{2}{8}=\frac{1}{4}\left(2y+\frac{1}{2}\right)+\frac{1}{2}
Multiply \frac{1}{8} and 2 to get \frac{2}{8}.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{4}\left(2y+\frac{1}{2}\right)+\frac{1}{2}
Reduce the fraction \frac{2}{8} to lowest terms by extracting and canceling out 2.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{4}\times 2y+\frac{1}{4}\times \frac{1}{2}+\frac{1}{2}
Use the distributive property to multiply \frac{1}{4} by 2y+\frac{1}{2}.
\frac{3}{8}y+\frac{1}{4}=\frac{2}{4}y+\frac{1}{4}\times \frac{1}{2}+\frac{1}{2}
Multiply \frac{1}{4} and 2 to get \frac{2}{4}.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{1}{4}\times \frac{1}{2}+\frac{1}{2}
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{1\times 1}{4\times 2}+\frac{1}{2}
Multiply \frac{1}{4} times \frac{1}{2} by multiplying numerator times numerator and denominator times denominator.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{1}{8}+\frac{1}{2}
Do the multiplications in the fraction \frac{1\times 1}{4\times 2}.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{1}{8}+\frac{4}{8}
Least common multiple of 8 and 2 is 8. Convert \frac{1}{8} and \frac{1}{2} to fractions with denominator 8.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{1+4}{8}
Since \frac{1}{8} and \frac{4}{8} have the same denominator, add them by adding their numerators.
\frac{3}{8}y+\frac{1}{4}=\frac{1}{2}y+\frac{5}{8}
Add 1 and 4 to get 5.
\frac{3}{8}y+\frac{1}{4}-\frac{1}{2}y=\frac{5}{8}
Subtract \frac{1}{2}y from both sides.
-\frac{1}{8}y+\frac{1}{4}=\frac{5}{8}
Combine \frac{3}{8}y and -\frac{1}{2}y to get -\frac{1}{8}y.
-\frac{1}{8}y=\frac{5}{8}-\frac{1}{4}
Subtract \frac{1}{4} from both sides.
-\frac{1}{8}y=\frac{5}{8}-\frac{2}{8}
Least common multiple of 8 and 4 is 8. Convert \frac{5}{8} and \frac{1}{4} to fractions with denominator 8.
-\frac{1}{8}y=\frac{5-2}{8}
Since \frac{5}{8} and \frac{2}{8} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{8}y=\frac{3}{8}
Subtract 2 from 5 to get 3.
y=\frac{3}{8}\left(-8\right)
Multiply both sides by -8, the reciprocal of -\frac{1}{8}.
y=\frac{3\left(-8\right)}{8}
Express \frac{3}{8}\left(-8\right) as a single fraction.
y=\frac{-24}{8}
Multiply 3 and -8 to get -24.
y=-3
Divide -24 by 8 to get -3.
