here is your answer by Sujeet,
Let to be 1/x=u
1/y=v

then,
by using cross multiple,
au-bv=0
ab²u+a²v-(a²+b²)=0

Now, you see in picture

Answer:

value of x = a and y = b

Step-by-step explanation:

Given System of equations:

\frac{a}{x}-\frac{b}{y}=0 ....................(1)

\frac{ab^2}{x}+\frac{a^2b}{y}=a^2+b^2 ..................(2)

Given equations are not linear.

let, 1/x = u and 1/y = v

we get

au - bv = 0 .....................(3)

ab²u + a²bv = a²+b² ................(4)

from equation 3,

u = bv/a

put this in eqn (4)

ab^2\times\frac{bv}{a}+a^2bv=a^2+b^2

b^3v+a^2bv=a^2+b^2

(b^2+a^2)bv=a^2+b^2

v=\frac{1}{b}

u=\frac{b\times\frac{1}{b}}{a}=\frac{1}{a}

So, 1/x = 1/a  ⇒ x = a

and 1/y = 1/b ⇒ y = b

Therefore, value of x = a and y = b
