Question

What system of equations does not have the same solution

Answer 1

2x + y = 4

4x + 2y = 12

Explanation:

Equations 2x + y = 4 & 4x + 2y = 12 haven't the same solution.

`2x + y = 4...(1) \\ 4x + 2y = 12 \\ 2(2x + y) = 12 \\ 2x + y = (12)/(2) \\ 2x + y = 6...(2) \\ rhs \: of \: equations \: (1) \: and \: (2) \: are \: \\ not \: sme.`
