Solve the system of equations by substitution. what is the solution for x? . 2x + y = 1 . 4x + 2y = −2

Given the system of equation:

2x+y = 1                   .....[1]

4x+2y = -2                .....[2]

We can write equation [1] as:

y = 1-2x

Substitute the value of y in [2] we have;

Using distributive property,

then;

Combine like terms;

     False.

Therefore, there is no solution and x = ∅

i think the answer would be c
