-\frac{3}{8}\left(-6\right)-\frac{3}{8}\left(-2\right)y=0.5\left(2y-3\right)-1
Use the distributive property to multiply -\frac{3}{8} by -6-2y.
\frac{-3\left(-6\right)}{8}-\frac{3}{8}\left(-2\right)y=0.5\left(2y-3\right)-1
Express -\frac{3}{8}\left(-6\right) as a single fraction.
\frac{18}{8}-\frac{3}{8}\left(-2\right)y=0.5\left(2y-3\right)-1
Multiply -3 and -6 to get 18.
\frac{9}{4}-\frac{3}{8}\left(-2\right)y=0.5\left(2y-3\right)-1
Reduce the fraction \frac{18}{8} to lowest terms by extracting and canceling out 2.
\frac{9}{4}+\frac{-3\left(-2\right)}{8}y=0.5\left(2y-3\right)-1
Express -\frac{3}{8}\left(-2\right) as a single fraction.
\frac{9}{4}+\frac{6}{8}y=0.5\left(2y-3\right)-1
Multiply -3 and -2 to get 6.
\frac{9}{4}+\frac{3}{4}y=0.5\left(2y-3\right)-1
Reduce the fraction \frac{6}{8} to lowest terms by extracting and canceling out 2.
\frac{9}{4}+\frac{3}{4}y=y-1.5-1
Use the distributive property to multiply 0.5 by 2y-3.
\frac{9}{4}+\frac{3}{4}y=y-2.5
Subtract 1 from -1.5 to get -2.5.
\frac{9}{4}+\frac{3}{4}y-y=-2.5
Subtract y from both sides.
\frac{9}{4}-\frac{1}{4}y=-2.5
Combine \frac{3}{4}y and -y to get -\frac{1}{4}y.
-\frac{1}{4}y=-2.5-\frac{9}{4}
Subtract \frac{9}{4} from both sides.
-\frac{1}{4}y=-\frac{5}{2}-\frac{9}{4}
Convert decimal number -2.5 to fraction -\frac{25}{10}. Reduce the fraction -\frac{25}{10} to lowest terms by extracting and canceling out 5.
-\frac{1}{4}y=-\frac{10}{4}-\frac{9}{4}
Least common multiple of 2 and 4 is 4. Convert -\frac{5}{2} and \frac{9}{4} to fractions with denominator 4.
-\frac{1}{4}y=\frac{-10-9}{4}
Since -\frac{10}{4} and \frac{9}{4} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{4}y=-\frac{19}{4}
Subtract 9 from -10 to get -19.
y=-\frac{19}{4}\left(-4\right)
Multiply both sides by -4, the reciprocal of -\frac{1}{4}.
y=\frac{-19\left(-4\right)}{4}
Express -\frac{19}{4}\left(-4\right) as a single fraction.
y=\frac{76}{4}
Multiply -19 and -4 to get 76.
y=19
Divide 76 by 4 to get 19.
