1. Problem Description

We are asked to evaluate the expression 12a+c\frac{12}{a} + c, given that a=3a = 3 and c=5c = 5.

2. Solution Steps

Substitute the given values of aa and cc into the expression:
12a+c=123+5\frac{12}{a} + c = \frac{12}{3} + 5
Now, we perform the division:
123=4\frac{12}{3} = 4
So, the expression becomes:
4+54 + 5
Finally, we perform the addition:
4+5=94 + 5 = 9

3. Final Answer

The final answer is 9.
