\frac{2}{5}x+1=\frac{3}{4}\left(x-1\right)
Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.
\frac{2}{5}x+1=\frac{3}{4}x+\frac{3}{4}\left(-1\right)
Use the distributive property to multiply \frac{3}{4} by x-1.
\frac{2}{5}x+1=\frac{3}{4}x-\frac{3}{4}
Multiply \frac{3}{4} and -1 to get -\frac{3}{4}.
\frac{2}{5}x+1-\frac{3}{4}x=-\frac{3}{4}
Subtract \frac{3}{4}x from both sides.
-\frac{7}{20}x+1=-\frac{3}{4}
Combine \frac{2}{5}x and -\frac{3}{4}x to get -\frac{7}{20}x.
-\frac{7}{20}x=-\frac{3}{4}-1
Subtract 1 from both sides.
-\frac{7}{20}x=-\frac{3}{4}-\frac{4}{4}
Convert 1 to fraction \frac{4}{4}.
-\frac{7}{20}x=\frac{-3-4}{4}
Since -\frac{3}{4} and \frac{4}{4} have the same denominator, subtract them by subtracting their numerators.
-\frac{7}{20}x=-\frac{7}{4}
Subtract 4 from -3 to get -7.
x=-\frac{7}{4}\left(-\frac{20}{7}\right)
Multiply both sides by -\frac{20}{7}, the reciprocal of -\frac{7}{20}.
x=\frac{-7\left(-20\right)}{4\times 7}
Multiply -\frac{7}{4} times -\frac{20}{7} by multiplying numerator times numerator and denominator times denominator.
x=\frac{140}{28}
Do the multiplications in the fraction \frac{-7\left(-20\right)}{4\times 7}.
x=5
Divide 140 by 28 to get 5.
