Explanation:

Step1: Isolate $\frac{m}{2}$

Subtract 9 from both sides:
$\frac{m}{2} + 9 - 9 = 12 - 9$
Simplify to get: $\frac{m}{2} = 3$

Step2: Solve for $m$

Multiply both sides by 2:
$\frac{m}{2} \times 2 = 3 \times 2$
Simplify to get: $m = 6$

Answer:

To isolate $\frac{m}{2}$, Subtract 9 on both sides.
The solution to the equation is $m=6$.
