\frac{3}{2}x+\frac{1}{2}-3=x
Divide each term of 3x+1 by 2 to get \frac{3}{2}x+\frac{1}{2}.
\frac{3}{2}x+\frac{1}{2}-\frac{6}{2}=x
Convert 3 to fraction \frac{6}{2}.
\frac{3}{2}x+\frac{1-6}{2}=x
Since \frac{1}{2} and \frac{6}{2} have the same denominator, subtract them by subtracting their numerators.
\frac{3}{2}x-\frac{5}{2}=x
Subtract 6 from 1 to get -5.
\frac{3}{2}x-\frac{5}{2}-x=0
Subtract x from both sides.
\frac{1}{2}x-\frac{5}{2}=0
Combine \frac{3}{2}x and -x to get \frac{1}{2}x.
\frac{1}{2}x=\frac{5}{2}
Add \frac{5}{2} to both sides. Anything plus zero gives itself.
x=\frac{5}{2}\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
x=5
Cancel out 2 and 2.
