3m - 2m = 12

what is M

3m - 2m = 12

m is a variable. In this equation, we need to find what m is equal to in order to make the equation true.

m = 12

by combining the like terms 3m and - 2m, we can find that m = 12.

If we plug 12 into each m variable in the original equation, the equation would be true.

3-2=1m = 12, so m=12. so m=12
