Answer 2

Answer:

$x + y = 5 \\ = > x = 5 - y \\ again \\ 2x - 3y = 4 \: putting \: the \: value \: of \: x \: we \: get \\ 2(5 - y) - 3y = 4 \\ = > 10 - 2y - 3y = 4 \\ = > 10 - 5y = 4 \\ = > - 5y = - 6 \\ = > y = \frac{6}{5} \\ so \: \: x = 5 - \frac{6}{5} \\ = \frac{25 - 6}{5} \\ = \frac{19}{5}$
