Answer:
B. 4x = -8
Step-by-step explanation:
We are given the system of equations,
2x + y - 4 = 0
2x - y - 4 = 0.
It is required to use the elimination method i.e. we remove the variable y from both the equations by applying some operation on them.
Now, on adding the equations, we get that y can be easily removed.
So, we are left with 4x - 8 = 0 i.e. 4x = -8.
Hence, by using the elimination method, if y is removed we get option B is correct.
