Answer 2

$2x + \: y = 8 \: \: \: \: \: \: \: \: ...(1) \\ x - 2y = - 1 \: \: \: \: ....(2) \\ multiply \: equation \: (1) \: by \: 2 \: we \: get \: \\ 4x + 2y = 16 \: \: \: \: ....(3) \\ x - 2y = - 1 \: \: \: \: \: ....(2) \\on \: \: adding \: equation(3) \: and \:( 2) \\ 5x = 15 \\ x = \frac{15}{5} \\ x = 3 \\ \: substitute \: the \: value \: of \: x \: in \: equation \: (1) \\ 2( 3 ) + y = 8 \\ 6 + y = 8 \\ y = 8 - 6 \\ y = 2$
