Answer:

The answer is C.

Step-by-step explanation:

In order to find the value of m, you have to eliminate -10 on the right side by adding 10 to both sides :

8 = -10 + m

8 + 10 = -10 + m + 10

18 = m

m = 18

8 = -10 + m

Move negative ten it the other side as a positive number

8+10 = m

18 = m
