\frac{3}{5}\times 2+\frac{3}{5}\left(-1\right)x=\frac{1}{4}\left(x-4\right)
Use the distributive property to multiply \frac{3}{5} by 2-x.
\frac{3\times 2}{5}+\frac{3}{5}\left(-1\right)x=\frac{1}{4}\left(x-4\right)
Express \frac{3}{5}\times 2 as a single fraction.
\frac{6}{5}+\frac{3}{5}\left(-1\right)x=\frac{1}{4}\left(x-4\right)
Multiply 3 and 2 to get 6.
\frac{6}{5}-\frac{3}{5}x=\frac{1}{4}\left(x-4\right)
Multiply \frac{3}{5} and -1 to get -\frac{3}{5}.
\frac{6}{5}-\frac{3}{5}x=\frac{1}{4}x+\frac{1}{4}\left(-4\right)
Use the distributive property to multiply \frac{1}{4} by x-4.
\frac{6}{5}-\frac{3}{5}x=\frac{1}{4}x+\frac{-4}{4}
Multiply \frac{1}{4} and -4 to get \frac{-4}{4}.
\frac{6}{5}-\frac{3}{5}x=\frac{1}{4}x-1
Divide -4 by 4 to get -1.
\frac{6}{5}-\frac{3}{5}x-\frac{1}{4}x=-1
Subtract \frac{1}{4}x from both sides.
\frac{6}{5}-\frac{17}{20}x=-1
Combine -\frac{3}{5}x and -\frac{1}{4}x to get -\frac{17}{20}x.
-\frac{17}{20}x=-1-\frac{6}{5}
Subtract \frac{6}{5} from both sides.
-\frac{17}{20}x=-\frac{5}{5}-\frac{6}{5}
Convert -1 to fraction -\frac{5}{5}.
-\frac{17}{20}x=\frac{-5-6}{5}
Since -\frac{5}{5} and \frac{6}{5} have the same denominator, subtract them by subtracting their numerators.
-\frac{17}{20}x=-\frac{11}{5}
Subtract 6 from -5 to get -11.
x=-\frac{11}{5}\left(-\frac{20}{17}\right)
Multiply both sides by -\frac{20}{17}, the reciprocal of -\frac{17}{20}.
x=\frac{-11\left(-20\right)}{5\times 17}
Multiply -\frac{11}{5} times -\frac{20}{17} by multiplying numerator times numerator and denominator times denominator.
x=\frac{220}{85}
Do the multiplications in the fraction \frac{-11\left(-20\right)}{5\times 17}.
x=\frac{44}{17}
Reduce the fraction \frac{220}{85} to lowest terms by extracting and canceling out 5.
