Answer 2

$\mathfrak \blue{19x - 17y = 55...eqn1}$

$\mathfrak \blue{17x - 19y = 53.....eqn2}$

$\mathfrak \blue{subtract \: equation \: 2 \: from \: 1}$

$\mathfrak \blue{now \: we \: get}$

$\mathfrak \blue{2x + 2y = 2}$

$\mathfrak \blue{put \: out \: common \: factor}$

$\mathfrak \blue{2(x + y) = 2}$

$\mathfrak \blue{x + y = \frac{2}{2} }$

$\mathfrak \blue{we \: get \: x + y = 1 \: so \: \: the \: value \: of \: x - y \: should \: be \: less \: than \: 1}$

$\mathfrak \blue{so \: option \: a) \: \frac{1}{3} \: or \: option \: b) - 3 \: are \: right}$

Hope it's help you.
