\frac{2\left(x-3\right)}{2x}\times \frac{3x}{1}
Factor the expressions that are not already factored in \frac{2x-6}{2x}.
\frac{x-3}{x}\times \frac{3x}{1}
Cancel out 2 in both numerator and denominator.
\frac{x-3}{x}\times 3x
Anything divided by one gives itself.
\frac{\left(x-3\right)\times 3}{x}x
Express \frac{x-3}{x}\times 3 as a single fraction.
\left(x-3\right)\times 3
Cancel out x and x.
3x-9
