Answer:

We solve the given system of equation by substitution method.

\frac{ax}{b}-\frac{by}{a}=a+b ...................... (1)

ax-by=2ab ....................(2)

First we find value of x from (2)

from (2), we get

ax=2ab+by

x=\frac{2ab+by}{a} ......... (3)

Now, We put value of x from (3) in (1), to get the value of y.

\frac{a\times\frac{2ab+by}{a}}{b}-\frac{by}{a}=a+b

\frac{2ab+by}{b}-\frac{by}{a}=a+b

\frac{a(2ab+by)-b^2y}{ab}=a+b

2a^2b-aby+b^2y=ab(a+b)

2a^2b+(ab-b^2)y=a^2b+ab^2

(ab-b^2)y=a^2b+ab^2-2a^2b

b(a-b)y=ab^2-a^2b

b(a-b)y=-ab(a-b)

y=\frac{-ab(a-b)}{b(a-b)}

y=-a

Finally to find the value of x we put value of y in (3)

x=\frac{2ab-ba}{a}

x=\frac{ab}{a}

x=b

Therefore, We get Value x = b & y = -a
