Solve the system by the elimination method. 2x + y - 4 = 0 2x - y - 4 = 0 when you eliminate y, what is the resulting equation? a) x = 0 b) 4x = -8 c) 4x = 8

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.
