\frac{3\left(-3x-1\right)}{12}-\frac{2\left(x-2\right)}{12}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 4 and 6 is 12. Multiply \frac{-3x-1}{4} times \frac{3}{3}. Multiply \frac{x-2}{6} times \frac{2}{2}.
\frac{3\left(-3x-1\right)-2\left(x-2\right)}{12}
Since \frac{3\left(-3x-1\right)}{12} and \frac{2\left(x-2\right)}{12} have the same denominator, subtract them by subtracting their numerators.
\frac{-9x-3-2x+4}{12}
Do the multiplications in 3\left(-3x-1\right)-2\left(x-2\right).
\frac{-11x+1}{12}
Combine like terms in -9x-3-2x+4.
