\frac{\left(14x-2\right)\left(x-6\right)}{\left(x-6\right)\left(x+16\right)}-\frac{\left(29-50x\right)\left(x+16\right)}{\left(x-6\right)\left(x+16\right)}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x+16 and x-6 is \left(x-6\right)\left(x+16\right). Multiply \frac{14x-2}{x+16} times \frac{x-6}{x-6}. Multiply \frac{29-50x}{x-6} times \frac{x+16}{x+16}.
\frac{\left(14x-2\right)\left(x-6\right)-\left(29-50x\right)\left(x+16\right)}{\left(x-6\right)\left(x+16\right)}
Since \frac{\left(14x-2\right)\left(x-6\right)}{\left(x-6\right)\left(x+16\right)} and \frac{\left(29-50x\right)\left(x+16\right)}{\left(x-6\right)\left(x+16\right)} have the same denominator, subtract them by subtracting their numerators.
