\frac{2\times 4a}{6x}-\frac{4\times 3}{6x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3x and 2x is 6x. Multiply \frac{4a}{3x} times \frac{2}{2}. Multiply \frac{4}{2x} times \frac{3}{3}.
\frac{2\times 4a-4\times 3}{6x}
Since \frac{2\times 4a}{6x} and \frac{4\times 3}{6x} have the same denominator, subtract them by subtracting their numerators.
\frac{8a-12}{6x}
Do the multiplications in 2\times 4a-4\times 3.
\frac{4\left(2a-3\right)}{6x}
Factor the expressions that are not already factored in \frac{8a-12}{6x}.
\frac{2\left(2a-3\right)}{3x}
Cancel out 2 in both numerator and denominator.
\frac{4a-6}{3x}
Use the distributive property to multiply 2 by 2a-3.
