\frac{1}{4}x+\frac{1}{4}\left(-2\right)=\frac{1}{3}\left(2x+6\right)
Use the distributive property to multiply \frac{1}{4} by x-2.
\frac{1}{4}x+\frac{-2}{4}=\frac{1}{3}\left(2x+6\right)
Multiply \frac{1}{4} and -2 to get \frac{-2}{4}.
\frac{1}{4}x-\frac{1}{2}=\frac{1}{3}\left(2x+6\right)
Reduce the fraction \frac{-2}{4} to lowest terms by extracting and canceling out 2.
\frac{1}{4}x-\frac{1}{2}=\frac{1}{3}\times 2x+\frac{1}{3}\times 6
Use the distributive property to multiply \frac{1}{3} by 2x+6.
\frac{1}{4}x-\frac{1}{2}=\frac{2}{3}x+\frac{1}{3}\times 6
Multiply \frac{1}{3} and 2 to get \frac{2}{3}.
\frac{1}{4}x-\frac{1}{2}=\frac{2}{3}x+\frac{6}{3}
Multiply \frac{1}{3} and 6 to get \frac{6}{3}.
\frac{1}{4}x-\frac{1}{2}=\frac{2}{3}x+2
Divide 6 by 3 to get 2.
\frac{1}{4}x-\frac{1}{2}-\frac{2}{3}x=2
Subtract \frac{2}{3}x from both sides.
-\frac{5}{12}x-\frac{1}{2}=2
Combine \frac{1}{4}x and -\frac{2}{3}x to get -\frac{5}{12}x.
-\frac{5}{12}x=2+\frac{1}{2}
Add \frac{1}{2} to both sides.
-\frac{5}{12}x=\frac{4}{2}+\frac{1}{2}
Convert 2 to fraction \frac{4}{2}.
-\frac{5}{12}x=\frac{4+1}{2}
Since \frac{4}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.
-\frac{5}{12}x=\frac{5}{2}
Add 4 and 1 to get 5.
x=\frac{5}{2}\left(-\frac{12}{5}\right)
Multiply both sides by -\frac{12}{5}, the reciprocal of -\frac{5}{12}.
x=\frac{5\left(-12\right)}{2\times 5}
Multiply \frac{5}{2} times -\frac{12}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-12}{2}
Cancel out 5 in both numerator and denominator.
x=-6
Divide -12 by 2 to get -6.
