-\frac{5}{6}x+\frac{3}{4}-\frac{1}{3}x=-\frac{5}{12}
Subtract \frac{1}{3}x from both sides.
-\frac{7}{6}x+\frac{3}{4}=-\frac{5}{12}
Combine -\frac{5}{6}x and -\frac{1}{3}x to get -\frac{7}{6}x.
-\frac{7}{6}x=-\frac{5}{12}-\frac{3}{4}
Subtract \frac{3}{4} from both sides.
-\frac{7}{6}x=-\frac{5}{12}-\frac{9}{12}
Least common multiple of 12 and 4 is 12. Convert -\frac{5}{12} and \frac{3}{4} to fractions with denominator 12.
-\frac{7}{6}x=\frac{-5-9}{12}
Since -\frac{5}{12} and \frac{9}{12} have the same denominator, subtract them by subtracting their numerators.
-\frac{7}{6}x=\frac{-14}{12}
Subtract 9 from -5 to get -14.
-\frac{7}{6}x=-\frac{7}{6}
Reduce the fraction \frac{-14}{12} to lowest terms by extracting and canceling out 2.
x=-\frac{7}{6}\left(-\frac{6}{7}\right)
Multiply both sides by -\frac{6}{7}, the reciprocal of -\frac{7}{6}.
x=\frac{-7\left(-6\right)}{6\times 7}
Multiply -\frac{7}{6} times -\frac{6}{7} by multiplying numerator times numerator and denominator times denominator.
x=\frac{42}{42}
Do the multiplications in the fraction \frac{-7\left(-6\right)}{6\times 7}.
x=1
Divide 42 by 42 to get 1.
