\frac{3\left(4y-5\right)}{6}-\frac{2y-1}{6}=y
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 6 is 6. Multiply \frac{4y-5}{2} times \frac{3}{3}.
\frac{3\left(4y-5\right)-\left(2y-1\right)}{6}=y
Since \frac{3\left(4y-5\right)}{6} and \frac{2y-1}{6} have the same denominator, subtract them by subtracting their numerators.
\frac{12y-15-2y+1}{6}=y
Do the multiplications in 3\left(4y-5\right)-\left(2y-1\right).
\frac{10y-14}{6}=y
Combine like terms in 12y-15-2y+1.
\frac{5}{3}y-\frac{7}{3}=y
Divide each term of 10y-14 by 6 to get \frac{5}{3}y-\frac{7}{3}.
\frac{5}{3}y-\frac{7}{3}-y=0
Subtract y from both sides.
\frac{2}{3}y-\frac{7}{3}=0
Combine \frac{5}{3}y and -y to get \frac{2}{3}y.
\frac{2}{3}y=\frac{7}{3}
Add \frac{7}{3} to both sides. Anything plus zero gives itself.
y=\frac{7}{3}\times \frac{3}{2}
Multiply both sides by \frac{3}{2}, the reciprocal of \frac{2}{3}.
y=\frac{7\times 3}{3\times 2}
Multiply \frac{7}{3} times \frac{3}{2} by multiplying numerator times numerator and denominator times denominator.
y=\frac{7}{2}
Cancel out 3 in both numerator and denominator.
