Answer 2

Answer:

$2x - y = 17.......i \\ x + 2y = 16........ii \\ \\ multiplying \: eq \: i \: by \: 2 \\ \\ 2(2x - y) = 17 \times 2 \\ \\ 4x - 2y = 34.....iii \\ \\ adding \: eq \: ii \: and \: iii \\ \\ \: \: \: \: \: \: \: \: \: x + 2y = 16 \\ ( + ) \: \: \: \: 4x - 2y = 34 \\ \\ 5x = 50 \\ \\ x = \frac{50}{5} = 10 \\ \\ x = 10 \\ \\ substituting \: the \: value \: of \: x \: in \: the \: equation \: ii \\ \\ 10 + 2y = 16 \\ \\ 2y = 16 - 10 \\ \\ y = \frac{6}{2} = 3 \\ \\ \\ so \: x = 10 \\ y = 3$
