\frac{5}{9}x-\frac{5}{3}-\frac{3}{4}x=-\frac{1}{2}
Subtract \frac{3}{4}x from both sides.
-\frac{7}{36}x-\frac{5}{3}=-\frac{1}{2}
Combine \frac{5}{9}x and -\frac{3}{4}x to get -\frac{7}{36}x.
-\frac{7}{36}x=-\frac{1}{2}+\frac{5}{3}
Add \frac{5}{3} to both sides.
-\frac{7}{36}x=-\frac{3}{6}+\frac{10}{6}
Least common multiple of 2 and 3 is 6. Convert -\frac{1}{2} and \frac{5}{3} to fractions with denominator 6.
-\frac{7}{36}x=\frac{-3+10}{6}
Since -\frac{3}{6} and \frac{10}{6} have the same denominator, add them by adding their numerators.
-\frac{7}{36}x=\frac{7}{6}
Add -3 and 10 to get 7.
x=\frac{7}{6}\left(-\frac{36}{7}\right)
Multiply both sides by -\frac{36}{7}, the reciprocal of -\frac{7}{36}.
x=\frac{7\left(-36\right)}{6\times 7}
Multiply \frac{7}{6} times -\frac{36}{7} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-36}{6}
Cancel out 7 in both numerator and denominator.
x=-6
Divide -36 by 6 to get -6.
