To solve the equation \(-7m = 42\), follow these steps:
Step 1: Add 7 to each side of the equation. (This step is not relevant here since we need to isolate \(m\), and we directly manipulate the equation as is.)
Step 2: Divide both sides of the equation by -7. \[ m = \frac{42}{-7} \]
Calculate the right side: \[ m = -6 \]
Thus, the solution to the equation is: m = -6
So, the correct response is m = -6.
In solving the equation \(-7m = 42\), the first step should involve isolating \(m\) on one side of the equation. Here’s how you can describe the first step clearly:
Step 1: Divide both sides of the equation by -7.
So, the equation becomes: \[ \frac{-7m}{-7} = \frac{42}{-7} \]
This simplifies to: \[ m = -6 \]
Therefore, Step 1 is to divide both sides by -7.
