\frac{2}{5}\times 2+\frac{2}{5}\left(-1\right)x=\frac{7}{4}\left(x-4\right)
Use the distributive property to multiply \frac{2}{5} by 2-x.
\frac{2\times 2}{5}+\frac{2}{5}\left(-1\right)x=\frac{7}{4}\left(x-4\right)
Express \frac{2}{5}\times 2 as a single fraction.
\frac{4}{5}+\frac{2}{5}\left(-1\right)x=\frac{7}{4}\left(x-4\right)
Multiply 2 and 2 to get 4.
\frac{4}{5}-\frac{2}{5}x=\frac{7}{4}\left(x-4\right)
Multiply \frac{2}{5} and -1 to get -\frac{2}{5}.
\frac{4}{5}-\frac{2}{5}x=\frac{7}{4}x+\frac{7}{4}\left(-4\right)
Use the distributive property to multiply \frac{7}{4} by x-4.
\frac{4}{5}-\frac{2}{5}x=\frac{7}{4}x+\frac{7\left(-4\right)}{4}
Express \frac{7}{4}\left(-4\right) as a single fraction.
\frac{4}{5}-\frac{2}{5}x=\frac{7}{4}x+\frac{-28}{4}
Multiply 7 and -4 to get -28.
\frac{4}{5}-\frac{2}{5}x=\frac{7}{4}x-7
Divide -28 by 4 to get -7.
\frac{4}{5}-\frac{2}{5}x-\frac{7}{4}x=-7
Subtract \frac{7}{4}x from both sides.
\frac{4}{5}-\frac{43}{20}x=-7
Combine -\frac{2}{5}x and -\frac{7}{4}x to get -\frac{43}{20}x.
-\frac{43}{20}x=-7-\frac{4}{5}
Subtract \frac{4}{5} from both sides.
-\frac{43}{20}x=-\frac{35}{5}-\frac{4}{5}
Convert -7 to fraction -\frac{35}{5}.
-\frac{43}{20}x=\frac{-35-4}{5}
Since -\frac{35}{5} and \frac{4}{5} have the same denominator, subtract them by subtracting their numerators.
-\frac{43}{20}x=-\frac{39}{5}
Subtract 4 from -35 to get -39.
x=-\frac{39}{5}\left(-\frac{20}{43}\right)
Multiply both sides by -\frac{20}{43}, the reciprocal of -\frac{43}{20}.
x=\frac{-39\left(-20\right)}{5\times 43}
Multiply -\frac{39}{5} times -\frac{20}{43} by multiplying numerator times numerator and denominator times denominator.
x=\frac{780}{215}
Do the multiplications in the fraction \frac{-39\left(-20\right)}{5\times 43}.
x=\frac{156}{43}
Reduce the fraction \frac{780}{215} to lowest terms by extracting and canceling out 5.
