\frac{1}{20}x+\frac{1}{12}\times 14+\frac{1}{12}\left(-1\right)x=1
Use the distributive property to multiply \frac{1}{12} by 14-x.
\frac{1}{20}x+\frac{14}{12}+\frac{1}{12}\left(-1\right)x=1
Multiply \frac{1}{12} and 14 to get \frac{14}{12}.
\frac{1}{20}x+\frac{7}{6}+\frac{1}{12}\left(-1\right)x=1
Reduce the fraction \frac{14}{12} to lowest terms by extracting and canceling out 2.
\frac{1}{20}x+\frac{7}{6}-\frac{1}{12}x=1
Multiply \frac{1}{12} and -1 to get -\frac{1}{12}.
-\frac{1}{30}x+\frac{7}{6}=1
Combine \frac{1}{20}x and -\frac{1}{12}x to get -\frac{1}{30}x.
-\frac{1}{30}x=1-\frac{7}{6}
Subtract \frac{7}{6} from both sides.
-\frac{1}{30}x=\frac{6}{6}-\frac{7}{6}
Convert 1 to fraction \frac{6}{6}.
-\frac{1}{30}x=\frac{6-7}{6}
Since \frac{6}{6} and \frac{7}{6} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{30}x=-\frac{1}{6}
Subtract 7 from 6 to get -1.
x=-\frac{1}{6}\left(-30\right)
Multiply both sides by -30, the reciprocal of -\frac{1}{30}.
x=\frac{-\left(-30\right)}{6}
Express -\frac{1}{6}\left(-30\right) as a single fraction.
x=\frac{30}{6}
Multiply -1 and -30 to get 30.
x=5
Divide 30 by 6 to get 5.
