\frac{3}{2}-\frac{8}{2}=x+\frac{6}{2}
Convert 4 to fraction \frac{8}{2}.
\frac{3-8}{2}=x+\frac{6}{2}
Since \frac{3}{2} and \frac{8}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{5}{2}=x+\frac{6}{2}
Subtract 8 from 3 to get -5.
-\frac{5}{2}=x+3
Divide 6 by 2 to get 3.
x+3=-\frac{5}{2}
Swap sides so that all variable terms are on the left hand side.
x=-\frac{5}{2}-3
Subtract 3 from both sides.
x=-\frac{5}{2}-\frac{6}{2}
Convert 3 to fraction \frac{6}{2}.
x=\frac{-5-6}{2}
Since -\frac{5}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.
x=-\frac{11}{2}
Subtract 6 from -5 to get -11.
