-5x-\frac{3}{2}-\frac{1}{4}x=-\frac{2}{3}
Subtract \frac{1}{4}x from both sides.
-\frac{21}{4}x-\frac{3}{2}=-\frac{2}{3}
Combine -5x and -\frac{1}{4}x to get -\frac{21}{4}x.
-\frac{21}{4}x=-\frac{2}{3}+\frac{3}{2}
Add \frac{3}{2} to both sides.
-\frac{21}{4}x=-\frac{4}{6}+\frac{9}{6}
Least common multiple of 3 and 2 is 6. Convert -\frac{2}{3} and \frac{3}{2} to fractions with denominator 6.
-\frac{21}{4}x=\frac{-4+9}{6}
Since -\frac{4}{6} and \frac{9}{6} have the same denominator, add them by adding their numerators.
-\frac{21}{4}x=\frac{5}{6}
Add -4 and 9 to get 5.
x=\frac{5}{6}\left(-\frac{4}{21}\right)
Multiply both sides by -\frac{4}{21}, the reciprocal of -\frac{21}{4}.
x=\frac{5\left(-4\right)}{6\times 21}
Multiply \frac{5}{6} times -\frac{4}{21} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-20}{126}
Do the multiplications in the fraction \frac{5\left(-4\right)}{6\times 21}.
x=-\frac{10}{63}
Reduce the fraction \frac{-20}{126} to lowest terms by extracting and canceling out 2.
