Answer:
Option C
Step-by-step explanation:
Step 1: Find the correct method
Option A is incorrect because we don't have m + 6 and 5m - 2
Option B is incorrect because that wouldn't show us the correct value
Option C is correct, once we solve for v, we can plug in v and get the value of m. For example: v + 6 = 5v - 2 → v + 8 = 5v → 8 = 4v → 2 = v. Then we plug it into the other equation m = 2 + 6 → m = 8
Option D is incorrect because that wouldn't show us the correct value.
