\frac{2\times 2y}{6xy}-\frac{3\times 3}{6xy}+\frac{8}{5xy}-\frac{5}{6x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3x and 2xy is 6xy. Multiply \frac{2}{3x} times \frac{2y}{2y}. Multiply \frac{3}{2xy} times \frac{3}{3}.
\frac{2\times 2y-3\times 3}{6xy}+\frac{8}{5xy}-\frac{5}{6x}
Since \frac{2\times 2y}{6xy} and \frac{3\times 3}{6xy} have the same denominator, subtract them by subtracting their numerators.
\frac{4y-9}{6xy}+\frac{8}{5xy}-\frac{5}{6x}
Do the multiplications in 2\times 2y-3\times 3.
\frac{5\left(4y-9\right)}{30xy}+\frac{8\times 6}{30xy}-\frac{5}{6x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 6xy and 5xy is 30xy. Multiply \frac{4y-9}{6xy} times \frac{5}{5}. Multiply \frac{8}{5xy} times \frac{6}{6}.
\frac{5\left(4y-9\right)+8\times 6}{30xy}-\frac{5}{6x}
Since \frac{5\left(4y-9\right)}{30xy} and \frac{8\times 6}{30xy} have the same denominator, add them by adding their numerators.
\frac{20y-45+48}{30xy}-\frac{5}{6x}
Do the multiplications in 5\left(4y-9\right)+8\times 6.
\frac{20y+3}{30xy}-\frac{5}{6x}
Combine like terms in 20y-45+48.
\frac{20y+3}{30xy}-\frac{5\times 5y}{30xy}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 30xy and 6x is 30xy. Multiply \frac{5}{6x} times \frac{5y}{5y}.
\frac{20y+3-5\times 5y}{30xy}
Since \frac{20y+3}{30xy} and \frac{5\times 5y}{30xy} have the same denominator, subtract them by subtracting their numerators.
\frac{20y+3-25y}{30xy}
Do the multiplications in 20y+3-5\times 5y.
\frac{-5y+3}{30xy}
Combine like terms in 20y+3-25y.
