Question

$\frac{m}{2} + 9 = 12$
$\\ \\ \\ \\ -9\\ \\ \\ -9$
$\frac{m}{2} = \square$

Explanation:

Step1: Subtract 9 from both sides

To solve for $\frac{m}{2}$, we subtract 9 from both sides of the equation $\frac{m}{2}+9 = 12$. So we have $\frac{m}{2}+9 - 9=12 - 9$.

Step2: Simplify both sides

Simplifying the left - hand side, $9 - 9 = 0$, so we get $\frac{m}{2}=\ 12-9$. Simplifying the right - hand side, $12-9 = 3$.
