2\times \frac{1}{6}-\frac{3}{4}\left(2x+18\right)=-4
Cancel out 3 and 3.
\frac{2}{6}-\frac{3}{4}\left(2x+18\right)=-4
Multiply 2 and \frac{1}{6} to get \frac{2}{6}.
\frac{1}{3}-\frac{3}{4}\left(2x+18\right)=-4
Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.
\frac{1}{3}-\frac{3}{4}\times 2x-\frac{3}{4}\times 18=-4
Use the distributive property to multiply -\frac{3}{4} by 2x+18.
\frac{1}{3}+\frac{-3\times 2}{4}x-\frac{3}{4}\times 18=-4
Express -\frac{3}{4}\times 2 as a single fraction.
\frac{1}{3}+\frac{-6}{4}x-\frac{3}{4}\times 18=-4
Multiply -3 and 2 to get -6.
\frac{1}{3}-\frac{3}{2}x-\frac{3}{4}\times 18=-4
Reduce the fraction \frac{-6}{4} to lowest terms by extracting and canceling out 2.
\frac{1}{3}-\frac{3}{2}x+\frac{-3\times 18}{4}=-4
Express -\frac{3}{4}\times 18 as a single fraction.
\frac{1}{3}-\frac{3}{2}x+\frac{-54}{4}=-4
Multiply -3 and 18 to get -54.
\frac{1}{3}-\frac{3}{2}x-\frac{27}{2}=-4
Reduce the fraction \frac{-54}{4} to lowest terms by extracting and canceling out 2.
\frac{2}{6}-\frac{3}{2}x-\frac{81}{6}=-4
Least common multiple of 3 and 2 is 6. Convert \frac{1}{3} and \frac{27}{2} to fractions with denominator 6.
\frac{2-81}{6}-\frac{3}{2}x=-4
Since \frac{2}{6} and \frac{81}{6} have the same denominator, subtract them by subtracting their numerators.
-\frac{79}{6}-\frac{3}{2}x=-4
Subtract 81 from 2 to get -79.
-\frac{3}{2}x=-4+\frac{79}{6}
Add \frac{79}{6} to both sides.
-\frac{3}{2}x=-\frac{24}{6}+\frac{79}{6}
Convert -4 to fraction -\frac{24}{6}.
-\frac{3}{2}x=\frac{-24+79}{6}
Since -\frac{24}{6} and \frac{79}{6} have the same denominator, add them by adding their numerators.
-\frac{3}{2}x=\frac{55}{6}
Add -24 and 79 to get 55.
x=\frac{55}{6}\left(-\frac{2}{3}\right)
Multiply both sides by -\frac{2}{3}, the reciprocal of -\frac{3}{2}.
x=\frac{55\left(-2\right)}{6\times 3}
Multiply \frac{55}{6} times -\frac{2}{3} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-110}{18}
Do the multiplications in the fraction \frac{55\left(-2\right)}{6\times 3}.
x=-\frac{55}{9}
Reduce the fraction \frac{-110}{18} to lowest terms by extracting and canceling out 2.
