\frac{1}{3}x+\frac{1}{3}\left(-2\right)-\frac{1}{2}\left(x+1\right)=\frac{5}{6}\left(x+2\right)
Use the distributive property to multiply \frac{1}{3} by x-2.
\frac{1}{3}x+\frac{-2}{3}-\frac{1}{2}\left(x+1\right)=\frac{5}{6}\left(x+2\right)
Multiply \frac{1}{3} and -2 to get \frac{-2}{3}.
\frac{1}{3}x-\frac{2}{3}-\frac{1}{2}\left(x+1\right)=\frac{5}{6}\left(x+2\right)
Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.
\frac{1}{3}x-\frac{2}{3}-\frac{1}{2}x-\frac{1}{2}=\frac{5}{6}\left(x+2\right)
Use the distributive property to multiply -\frac{1}{2} by x+1.
-\frac{1}{6}x-\frac{2}{3}-\frac{1}{2}=\frac{5}{6}\left(x+2\right)
Combine \frac{1}{3}x and -\frac{1}{2}x to get -\frac{1}{6}x.
-\frac{1}{6}x-\frac{4}{6}-\frac{3}{6}=\frac{5}{6}\left(x+2\right)
Least common multiple of 3 and 2 is 6. Convert -\frac{2}{3} and \frac{1}{2} to fractions with denominator 6.
-\frac{1}{6}x+\frac{-4-3}{6}=\frac{5}{6}\left(x+2\right)
Since -\frac{4}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{6}x-\frac{7}{6}=\frac{5}{6}\left(x+2\right)
Subtract 3 from -4 to get -7.
-\frac{1}{6}x-\frac{7}{6}=\frac{5}{6}x+\frac{5}{6}\times 2
Use the distributive property to multiply \frac{5}{6} by x+2.
-\frac{1}{6}x-\frac{7}{6}=\frac{5}{6}x+\frac{5\times 2}{6}
Express \frac{5}{6}\times 2 as a single fraction.
-\frac{1}{6}x-\frac{7}{6}=\frac{5}{6}x+\frac{10}{6}
Multiply 5 and 2 to get 10.
-\frac{1}{6}x-\frac{7}{6}=\frac{5}{6}x+\frac{5}{3}
Reduce the fraction \frac{10}{6} to lowest terms by extracting and canceling out 2.
-\frac{1}{6}x-\frac{7}{6}-\frac{5}{6}x=\frac{5}{3}
Subtract \frac{5}{6}x from both sides.
-x-\frac{7}{6}=\frac{5}{3}
Combine -\frac{1}{6}x and -\frac{5}{6}x to get -x.
-x=\frac{5}{3}+\frac{7}{6}
Add \frac{7}{6} to both sides.
-x=\frac{10}{6}+\frac{7}{6}
Least common multiple of 3 and 6 is 6. Convert \frac{5}{3} and \frac{7}{6} to fractions with denominator 6.
-x=\frac{10+7}{6}
Since \frac{10}{6} and \frac{7}{6} have the same denominator, add them by adding their numerators.
-x=\frac{17}{6}
Add 10 and 7 to get 17.
x=-\frac{17}{6}
Multiply both sides by -1.
