\frac{5}{12}-\frac{3}{8}-\left(-x\right)=-\frac{5}{6}
To find the opposite of \frac{3}{8}-x, find the opposite of each term.
\frac{5}{12}-\frac{3}{8}+x=-\frac{5}{6}
The opposite of -x is x.
\frac{10}{24}-\frac{9}{24}+x=-\frac{5}{6}
Least common multiple of 12 and 8 is 24. Convert \frac{5}{12} and \frac{3}{8} to fractions with denominator 24.
\frac{10-9}{24}+x=-\frac{5}{6}
Since \frac{10}{24} and \frac{9}{24} have the same denominator, subtract them by subtracting their numerators.
\frac{1}{24}+x=-\frac{5}{6}
Subtract 9 from 10 to get 1.
x=-\frac{5}{6}-\frac{1}{24}
Subtract \frac{1}{24} from both sides.
x=-\frac{20}{24}-\frac{1}{24}
Least common multiple of 6 and 24 is 24. Convert -\frac{5}{6} and \frac{1}{24} to fractions with denominator 24.
x=\frac{-20-1}{24}
Since -\frac{20}{24} and \frac{1}{24} have the same denominator, subtract them by subtracting their numerators.
x=\frac{-21}{24}
Subtract 1 from -20 to get -21.
x=-\frac{7}{8}
Reduce the fraction \frac{-21}{24} to lowest terms by extracting and canceling out 3.
