\frac{1}{4}\times 4x+\frac{1}{4}\left(-1\right)=-\frac{1}{5}-\frac{2}{5}
Use the distributive property to multiply \frac{1}{4} by 4x-1.
x+\frac{1}{4}\left(-1\right)=-\frac{1}{5}-\frac{2}{5}
Cancel out 4 and 4.
x-\frac{1}{4}=-\frac{1}{5}-\frac{2}{5}
Multiply \frac{1}{4} and -1 to get -\frac{1}{4}.
x-\frac{1}{4}=\frac{-1-2}{5}
Since -\frac{1}{5} and \frac{2}{5} have the same denominator, subtract them by subtracting their numerators.
x-\frac{1}{4}=-\frac{3}{5}
Subtract 2 from -1 to get -3.
x=-\frac{3}{5}+\frac{1}{4}
Add \frac{1}{4} to both sides.
x=-\frac{12}{20}+\frac{5}{20}
Least common multiple of 5 and 4 is 20. Convert -\frac{3}{5} and \frac{1}{4} to fractions with denominator 20.
x=\frac{-12+5}{20}
Since -\frac{12}{20} and \frac{5}{20} have the same denominator, add them by adding their numerators.
x=-\frac{7}{20}
Add -12 and 5 to get -7.
