Mathematics

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;

4x+2(1-2x) = -2

Using distributive property, $a \cdot(b+c) = a\cdot b+ a\cdot c$

then;

4x+2-4x = -2

Combine like terms;

2= -2 False.

Therefore, there is no solution and x = ∅
