\frac{2\left(5-x\right)}{6x}-\frac{3\left(x-4\right)}{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{5-x}{3x} times \frac{2}{2}. Multiply \frac{x-4}{2x} times \frac{3}{3}.
\frac{2\left(5-x\right)-3\left(x-4\right)}{6x}
Since \frac{2\left(5-x\right)}{6x} and \frac{3\left(x-4\right)}{6x} have the same denominator, subtract them by subtracting their numerators.
\frac{10-2x-3x+12}{6x}
Do the multiplications in 2\left(5-x\right)-3\left(x-4\right).
\frac{22-5x}{6x}
Combine like terms in 10-2x-3x+12.
