x-\frac{1}{2}-3x-3=2\left(x+\frac{1}{4}\right)
Use the distributive property to multiply -3 by x+1.
-2x-\frac{1}{2}-3=2\left(x+\frac{1}{4}\right)
Combine x and -3x to get -2x.
-2x-\frac{1}{2}-\frac{6}{2}=2\left(x+\frac{1}{4}\right)
Convert 3 to fraction \frac{6}{2}.
-2x+\frac{-1-6}{2}=2\left(x+\frac{1}{4}\right)
Since -\frac{1}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.
-2x-\frac{7}{2}=2\left(x+\frac{1}{4}\right)
Subtract 6 from -1 to get -7.
-2x-\frac{7}{2}=2x+2\times \frac{1}{4}
Use the distributive property to multiply 2 by x+\frac{1}{4}.
-2x-\frac{7}{2}=2x+\frac{2}{4}
Multiply 2 and \frac{1}{4} to get \frac{2}{4}.
-2x-\frac{7}{2}=2x+\frac{1}{2}
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
-2x-\frac{7}{2}-2x=\frac{1}{2}
Subtract 2x from both sides.
-4x-\frac{7}{2}=\frac{1}{2}
Combine -2x and -2x to get -4x.
-4x=\frac{1}{2}+\frac{7}{2}
Add \frac{7}{2} to both sides.
-4x=\frac{1+7}{2}
Since \frac{1}{2} and \frac{7}{2} have the same denominator, add them by adding their numerators.
-4x=\frac{8}{2}
Add 1 and 7 to get 8.
-4x=4
Divide 8 by 2 to get 4.
x=\frac{4}{-4}
Divide both sides by -4.
x=-1
Divide 4 by -4 to get -1.
