Question

how can you isolate the expression \\(\frac{m}{2}\\)? \\(\frac{m}{2} + 9 = 12\\) ? on both sides. options: add, subtract, multiply by, divide by

Explanation:

Step1: Identify the operation to isolate $\frac{m}{2}$

To isolate $\frac{m}{2}$ in the equation $\frac{m}{2}+9 = 12$, we need to reverse the operation that is being done to $\frac{m}{2}$. The term $+9$ is added to $\frac{m}{2}$, so we use the inverse operation of addition, which is subtraction. We subtract 9 from both sides of the equation.

Step2: Perform the operation

Subtract 9 from both sides: $\frac{m}{2}+9 - 9=12 - 9$, which simplifies to $\frac{m}{2}=3$. So the operation is to subtract 9.

Answer:

Subtract, 9
