What system of equations does not have the same solution

Answer:
2x + y = 4
4x + 2y = 12
Step-by-step explanation:
Equations 2x + y = 4 & 4x + 2y = 12 haven't the same solution.
[tex]2x + y = 4...(1) \\ 4x + 2y = 12 \\ 2(2x + y) = 12 \\ 2x + y = \frac{12}{2} \\ 2x + y = 6...(2) \\ rhs \: of \: equations \: (1) \: and \: (2) \: are \: \\ not \: sme.[/tex]
