1. 2/√x+ 3/√y= 2,4/√ x-9/√y= -1​

Answer 1

Answer:

I do t know the answer

Step-by-step explanation:

please make me BRAINALIST

Answer 2

Step-by-step explanation:

Given pair of linear equations are

2/√x+ 3/√y= 2, 4/√ x-9/√y= -1

put 1/√x=a and 1/√y=b then

2a+3b=2-----(1)×2=>4a+6b=4

4a-9b=-1-----(2)×1=>4a-9b=-1

(-)

-------------------

0+15b=5

--------------------

=>15b=5

=>b=5/15

=>b=1/3

and from (1)

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

=>2a+3/3=2

=>2a+1=2

=>2a=2-1

=>2a=1

=>a=1/2

now,a=1/2=1/√x

=>√x=2

=>x=4

and b=1/3=1/√y

=>√y=3

=>y=9

Answer:-

The solution of the given pair of linear equations is (4,9)
