6x\left(\frac{2}{6}-\frac{3}{6}\right)-\frac{3^{2}}{-12}
Least common multiple of 3 and 2 is 6. Convert \frac{1}{3} and \frac{1}{2} to fractions with denominator 6.
6x\times \frac{2-3}{6}-\frac{3^{2}}{-12}
Since \frac{2}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
6x\left(-\frac{1}{6}\right)-\frac{3^{2}}{-12}
Subtract 3 from 2 to get -1.
-x-\frac{3^{2}}{-12}
Cancel out 6 and 6.
-x-\frac{9}{-12}
Calculate 3 to the power of 2 and get 9.
-x-\left(-\frac{3}{4}\right)
Reduce the fraction \frac{9}{-12} to lowest terms by extracting and canceling out 3.
-x+\frac{3}{4}
The opposite of -\frac{3}{4} is \frac{3}{4}.
