Quizplus · Accepted Answer

To add or subtract fractions, they must have a common denominator. The common denominator for $\frac{5}{14}$ and $\frac{6}{7x}$ is $14x$. Convert each fraction: $-\frac{5}{14} = -\frac{5x}{14x}$ and $-\frac{6}{7x} = -\frac{12}{14x}$. Adding these gives $-\frac{5x}{14x} - \frac{12}{14x} = \frac{-5x-12}{14x}$.
