Answer:

In-depth explanation:
Hi there, let's solve this equation,
Recall that all equations aim for the same thing, which is isolating the variable. For this equation the variable is m, so we will find a way to isolate it.
Our equation is m - 5 = 0.
To isolate m, I will add 5 to each side of the equation:
m - 5 + 5 = 0 + 5
On the left hand side we're left with m, and on the right side we have 5:
m = 5
