1. **State the problem:** Find the value of the expression $$\frac{3m+2n}{3k-2m}$$ when $$m=4$$, $$n$$ is missing (assumed to be 0), and $$k=5$$. 2. **Substitute the known values:** Since $$n$$ is not given, we assume $$n=0$$. $$\frac{3(4)+2(0)}{3(5)-2(4)} = \frac{12+0}{15-8}$$ 3. **Simplify numerator and denominator:** $$\frac{12}{7}$$ 4. **Final answer:** $$\frac{12}{7}$$ or approximately 1.714. Note: If $$n$$ is provided, substitute that value instead for accurate calculation.
