Question

x+y=3
2x+y=-2 by cross multiplication​

Answer 1

Answer:

$x + y = 3....(1)$

$2x + y = - 2.....(2)$

$multiply \: eqn \: (1) \: by \: 2 \: and \: subtract \: with \: (2)$

$2x + 2y = 6.....(3)$

$2x + y = - 2......(4)$

$y = 8$

$put \: tha \: value \: of \: y \: in \: eqn \: (1)$

$x = - 5$
