The problem is to solve the equation $9 = 15 + \frac{m}{3}$ for the variable $m$.

1. Problem Description

The problem is to solve the equation $9 = 15 + \frac{m}{3}$ for the variable $m$.

2. Solution Steps

To solve for $m$, we need to isolate it.

First, subtract 15 from both sides of the equation:

$9 - 15 = 15 + \frac{m}{3} - 15$

$-6 = \frac{m}{3}$

Next, multiply both sides of the equation by 3 to isolate $m$:

$3 * (-6) = 3 * \frac{m}{3}$

$-18 = m$

3. Final Answer

The value of $m$ is -

1

8. $m = -18$
