Question

solve the following pairs of equations by reducing them to a pair of linear equations 2 by root x + 3 by root Y is equal to 2 and 4 by root x minus nine by root Y is equal to -1​

Answer 1

Step-by-step explanation:

consider 1/√x and 1/√y to be a and b

so,.

2a+3b=2

4a-9b=-1

on solving these, 15b =3. so b =1/5.

and a=7/10

so, y=25 and X= 100/49
