Answer 1

Step-by-step explanation:

1/√x = a, 1/√y =b

2a + 3b = 2 ---------(1)

4a - 9b = -1 -----------(2)

Multiply equation 1 by 4 and equation 2 by 2.

4(2a +3b =2) , 2( 4a - 9b = -1)

8a + 12b = 8 , 8a - 18b = -2

subtract

8a + 12b = 8

8a - 18 b = -2

- + +

=> 30b = 10

b = 1/3

2a+3b =2

2a+3(1/3)=2l

2a =2-1

2a =1

a= 1/2

put value 1/√x = a = 1/2

( 1/√x) ^2 = ( 1/2)^2

1/x = 1/4

x = 4

1 / √y = b = 1/3

(1/√y) ^2 = (1/3)^2

y = 9
