3x-11-\frac{1}{6}\times 7x-\frac{1}{6}\times 8=x-4
Use the distributive property to multiply -\frac{1}{6} by 7x+8.
3x-11+\frac{-7}{6}x-\frac{1}{6}\times 8=x-4
Express -\frac{1}{6}\times 7 as a single fraction.
3x-11-\frac{7}{6}x-\frac{1}{6}\times 8=x-4
Fraction \frac{-7}{6} can be rewritten as -\frac{7}{6} by extracting the negative sign.
3x-11-\frac{7}{6}x+\frac{-8}{6}=x-4
Express -\frac{1}{6}\times 8 as a single fraction.
3x-11-\frac{7}{6}x-\frac{4}{3}=x-4
Reduce the fraction \frac{-8}{6} to lowest terms by extracting and canceling out 2.
\frac{11}{6}x-11-\frac{4}{3}=x-4
Combine 3x and -\frac{7}{6}x to get \frac{11}{6}x.
\frac{11}{6}x-\frac{33}{3}-\frac{4}{3}=x-4
Convert -11 to fraction -\frac{33}{3}.
\frac{11}{6}x+\frac{-33-4}{3}=x-4
Since -\frac{33}{3} and \frac{4}{3} have the same denominator, subtract them by subtracting their numerators.
\frac{11}{6}x-\frac{37}{3}=x-4
Subtract 4 from -33 to get -37.
\frac{11}{6}x-\frac{37}{3}-x=-4
Subtract x from both sides.
\frac{5}{6}x-\frac{37}{3}=-4
Combine \frac{11}{6}x and -x to get \frac{5}{6}x.
\frac{5}{6}x=-4+\frac{37}{3}
Add \frac{37}{3} to both sides.
\frac{5}{6}x=-\frac{12}{3}+\frac{37}{3}
Convert -4 to fraction -\frac{12}{3}.
\frac{5}{6}x=\frac{-12+37}{3}
Since -\frac{12}{3} and \frac{37}{3} have the same denominator, add them by adding their numerators.
\frac{5}{6}x=\frac{25}{3}
Add -12 and 37 to get 25.
x=\frac{25}{3}\times \frac{6}{5}
Multiply both sides by \frac{6}{5}, the reciprocal of \frac{5}{6}.
x=\frac{25\times 6}{3\times 5}
Multiply \frac{25}{3} times \frac{6}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{150}{15}
Do the multiplications in the fraction \frac{25\times 6}{3\times 5}.
x=10
Divide 150 by 15 to get 10.
