Subtract. \( \frac{5}{a-3}-\frac{a}{a-3} \) Simplify your answer as much as possible.

To subtract the fractions \(\frac{5}{a-3}\) and \(\frac{a}{a-3}\), follow these steps: 1. **Common Denominator:** Both fractions already have the same denominator, \(a - 3\). 2. **Subtract the Numerators:** \[ \frac{5}{a-3} - \frac{a}{a-3} = \frac{5 - a}{a-3} \] 3. **Simplify (Optional):** You can also factor out a \(-1\) from the numerator if desired: \[ \frac{5 - a}{a-3} = \frac{-(a - 5)}{a-3} = \frac{a - 5}{3 - a} \] However, \(\frac{5 - a}{a-3}\) is typically sufficient. **Final Answer:** \[ \frac{5 - a}{a - 3} \]
