Find the value of the variable.
$12 = \frac{e}{2}$

Short Answer

Expert verified

The value of the variable is $e = 24$ .

Step by step solution

Step 1. Multiply by 2.

To find the value of the variable in the equation $12 = \frac{e}{2}$ , multiply both sides of the equation by 2.

$12 \times 2 = \frac{e}{2} \times 2$

Step 2. Simplify the equation.

To further simplify, cancel the common factor of 2 on the right-hand side of the equation.

$\begin{array}{l} 12 \times 2 = \frac{e}{2} \times 2 \\ 24 = e \end{array}$

Step 3. Verify the value.

In order to verify the value of e, substitute 24 for into the equation $12 = \frac{e}{2}$ .

$\begin{array}{l} 12 = \frac{24}{2} \\ 12 = 12 True \end{array}$

Hence, the value of the variable is $e = 24$ .
