\frac{3}{8}x-\frac{5}{9}+\frac{4}{5}y+\frac{6}{9}+\frac{3}{4}x+\frac{6}{5}y
Least common multiple of 9 and 3 is 9. Convert -\frac{5}{9} and \frac{2}{3} to fractions with denominator 9.
\frac{3}{8}x+\frac{-5+6}{9}+\frac{4}{5}y+\frac{3}{4}x+\frac{6}{5}y
Since -\frac{5}{9} and \frac{6}{9} have the same denominator, add them by adding their numerators.
\frac{3}{8}x+\frac{1}{9}+\frac{4}{5}y+\frac{3}{4}x+\frac{6}{5}y
Add -5 and 6 to get 1.
\frac{9}{8}x+\frac{1}{9}+\frac{4}{5}y+\frac{6}{5}y
Combine \frac{3}{8}x and \frac{3}{4}x to get \frac{9}{8}x.
\frac{9}{8}x+\frac{1}{9}+2y
Combine \frac{4}{5}y and \frac{6}{5}y to get 2y.
