\frac{3}{2}x-1+3x=\frac{1}{2}
Add 3x to both sides.
\frac{9}{2}x-1=\frac{1}{2}
Combine \frac{3}{2}x and 3x to get \frac{9}{2}x.
\frac{9}{2}x=\frac{1}{2}+1
Add 1 to both sides.
\frac{9}{2}x=\frac{1}{2}+\frac{2}{2}
Convert 1 to fraction \frac{2}{2}.
\frac{9}{2}x=\frac{1+2}{2}
Since \frac{1}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.
\frac{9}{2}x=\frac{3}{2}
Add 1 and 2 to get 3.
x=\frac{3}{2}\times \frac{2}{9}
Multiply both sides by \frac{2}{9}, the reciprocal of \frac{9}{2}.
x=\frac{3\times 2}{2\times 9}
Multiply \frac{3}{2} times \frac{2}{9} by multiplying numerator times numerator and denominator times denominator.
x=\frac{3}{9}
Cancel out 2 in both numerator and denominator.
x=\frac{1}{3}
Reduce the fraction \frac{3}{9} to lowest terms by extracting and canceling out 3.
