Answer 2

$\large \bigstar \: \: \bold{ \frac{2x}{a} + \frac{y}{b} = 2}$

$\large \bigstar \: \: \: \bold{ \frac{x}{a} - \frac{y}{b} = 4}$

$\large \implies \: \rm{2bx + ay = 2ab}$

~Add the two equations

$\large \implies \rm \: 3bx = 6ab$

$\large \implies \rm \: x = 2a$

~Now,

$\large \rm \: 2b(2a) + ay = 2ab$

$\large \color{red}{ \underline{ \implies \rm \: ay = - 2ab}}$

$\large \color{red}{ \underline{ \implies \rm \: y = - 2b}}$
