Take Matrics in use.
2x + y = 1 ----> y = -2x + 1 now sub -2x + 1 in for y in the other equation 4x + 2y = -1 4x + 2(-2x + 1) = -1 -- distribute 4x - 4x + 2 = -1 -- subtract 2 from both sides 4x - 4x = -1 - 2 -- combine like terms 0 = -3 (incorrect) There is no x value.There is no solution.
thanks highly appreciated @texaschic101
