Answer 1

To solve for m, we can isolate the variable by performing inverse operations.

First, add 9 to both sides of the equation:

2m - 9 + 9 = 21 + 9

This simplifies to:

2m = 30

Next, divide both sides of the equation by 2 to solve for m:

2m/2 = 30/2

This simplifies to:

m = 15

Therefore, the solution for m is 15.
