Answer 2

Answer:

x = 4 &

y = 9

Step-by-step explanation:

$x + y = 5 \: \: - (i) \\ 2x + y = 1 \: - (ii) \\ multiply \: (i) \: by \: 2 \: and \: (ii) \: by \: 1 \\ 2x + 2y = 10 \: - (iii) \\ 2x + y = 1 \: - (iv) \\ \: \: \: \: \:- \: \: \: \: \: - \: \: \: \: \: \: \: \: \: \: \: - \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ - - - - - - - - - - \\ y = 9 \: put \: in \: (i)\: equation \\ x + 9 = 5 \\ x = 5 - 9 \\ x = - 4$
