\frac{7}{10}\left(-\frac{5}{6}\right)+x\left(\frac{2}{3}-\frac{1}{2}\right)=-\frac{5}{12}
Convert decimal number 0.7 to fraction \frac{7}{10}.
\frac{7\left(-5\right)}{10\times 6}+x\left(\frac{2}{3}-\frac{1}{2}\right)=-\frac{5}{12}
Multiply \frac{7}{10} times -\frac{5}{6} by multiplying numerator times numerator and denominator times denominator.
\frac{-35}{60}+x\left(\frac{2}{3}-\frac{1}{2}\right)=-\frac{5}{12}
Do the multiplications in the fraction \frac{7\left(-5\right)}{10\times 6}.
-\frac{7}{12}+x\left(\frac{2}{3}-\frac{1}{2}\right)=-\frac{5}{12}
Reduce the fraction \frac{-35}{60} to lowest terms by extracting and canceling out 5.
-\frac{7}{12}+x\left(\frac{4}{6}-\frac{3}{6}\right)=-\frac{5}{12}
Least common multiple of 3 and 2 is 6. Convert \frac{2}{3} and \frac{1}{2} to fractions with denominator 6.
-\frac{7}{12}+x\times \frac{4-3}{6}=-\frac{5}{12}
Since \frac{4}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
-\frac{7}{12}+x\times \frac{1}{6}=-\frac{5}{12}
Subtract 3 from 4 to get 1.
x\times \frac{1}{6}=-\frac{5}{12}+\frac{7}{12}
Add \frac{7}{12} to both sides.
x\times \frac{1}{6}=\frac{-5+7}{12}
Since -\frac{5}{12} and \frac{7}{12} have the same denominator, add them by adding their numerators.
x\times \frac{1}{6}=\frac{2}{12}
Add -5 and 7 to get 2.
x\times \frac{1}{6}=\frac{1}{6}
Reduce the fraction \frac{2}{12} to lowest terms by extracting and canceling out 2.
x=\frac{1}{6}\times 6
Multiply both sides by 6, the reciprocal of \frac{1}{6}.
x=1
Cancel out 6 and 6.
