Answer:

m = -2

Step-by-step explanation:

Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.

M= -2 because you divide both side by 7 to get m+5=3 then subtract 5 from both sides to get m=-2
