pls ans this asap.........​

Answer 1

Given :-

2/√x + 3/√y = -1

4/√x - 9/√y = 1

Let,

1/√x = a and 1/√y = b

[2a + 3b = -1 ] × 4 ---(1)

[4a - 9b = 1 ] × 2 ----(2)

8a + 12b = -4

8a - 18b = 2

- + -

_____________

30b = -6

b = -1/5

Putting 'b' in 1

2a + 3 × -1/5 = -1

2a = -1 + 5/3

2a = -2/3

a = -1/3

b = -1/5

1/√x = -1/3

√x = -3

On squaring both sides,

x = 9

similarly,

y = 25
