\frac{3\times 3}{3\left(2x-1\right)}+\frac{2}{3\left(2x-1\right)}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2x-1 and 3\left(2x-1\right) is 3\left(2x-1\right). Multiply \frac{3}{2x-1} times \frac{3}{3}.
\frac{3\times 3+2}{3\left(2x-1\right)}
Since \frac{3\times 3}{3\left(2x-1\right)} and \frac{2}{3\left(2x-1\right)} have the same denominator, add them by adding their numerators.
