\frac{3}{x-4}+\frac{2}{5\left(x-4\right)}
Factor 5x-20.
\frac{3\times 5}{5\left(x-4\right)}+\frac{2}{5\left(x-4\right)}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x-4 and 5\left(x-4\right) is 5\left(x-4\right). Multiply \frac{3}{x-4} times \frac{5}{5}.
\frac{3\times 5+2}{5\left(x-4\right)}
Since \frac{3\times 5}{5\left(x-4\right)} and \frac{2}{5\left(x-4\right)} have the same denominator, add them by adding their numerators.
\frac{15+2}{5\left(x-4\right)}
Do the multiplications in 3\times 5+2.
\frac{17}{5\left(x-4\right)}
Do the calculations in 15+2.
\frac{17}{5x-20}
