Question

Solve by cross multiplication method: a/x - b/y = 0 ; ab2/x + a2b/x = a2 + b2

Answer 1

Answer:

value of x = a and y = b

Step-by-step explanation:

Given System of equations:

....................(1)

..................(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)

So, 1/x = 1/a  ⇒ x = a

and 1/y = 1/b ⇒ y = b

Therefore, value of x = a and y = b
