1. **State the problem:** Simplify the expression $\frac{X}{3} + 5$ or rewrite it in a clearer form. 2. **Understand the expression:** The expression consists of a fraction $\frac{X}{3}$ plus the number 5. 3. **No further simplification is possible** unless we combine into a single fraction: $$\frac{X}{3} + 5 = \frac{X}{3} + \frac{5 \times 3}{3} = \frac{X}{3} + \frac{15}{3}$$ 4. **Add the fractions:** $$\frac{X}{3} + \frac{15}{3} = \frac{X + 15}{3}$$ 5. **Final answer:** The simplified form of the expression is $$\frac{X + 15}{3}$$ This means you can write $\frac{X}{3} + 5$ as a single fraction with denominator 3.
