Answer 1

Answer:

hey here is your answer

pls mark it as brainliest pls

Step-by-step explanation:

$so \: here \: given \: linear \: equations \: are \: \\ \frac{ax}{b} - \frac{by}{a} = a + b \\ ie \: \: \frac{a {}^{2} x - b {}^{2}y }{ab} = a + b \\ a {}^{2}x - b {}^{2} y = a {}^{2} b + ab {}^{2} \: \: \: \: \: \: \: \: \: \: \: (1) \\ax - by = 2ab \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (2)$

$multiplying \: \: (2) \: by \: b \\ we \: get \\ bax - b {}^{2} y = 2ab {}^{2} \: \: \: \: \: \: \: \: \: \: \: \: (3) \\ subtracting \: now \: (1) \: from \: (3) \\ we \: get \\ \\ bax - a {}^{2} x = ab {}^{2} - a {}^{2} b \\ ax(b - a) = ab(b - a) \\ ie \: \: ax = ab \\ so \: \: hence \: \: x = b$

$substitute \: value \: of \: x \: in \: any \: of \: three \: equations \: \\ we \: get \\ y = - a \\ \\ hence \: \: (x,y) = ( b,-a) \: is \: solution \: of \: above \: linear \: equations \:$
