Answer 1

Answer:

sorry don't know

Step-by-step explanation:

Answer 2

Answer:

x=4 and y=9

Step-by-step explanation:

Given equations are 2/√x+3/√y=2

4/√x-9/√y= -1

Let 1/√x = p and 1/√y = q then

given equations converted into 2p+3q=2 and 4p - 9q= -1

by solving the above equations using elimination method

3( 2p+3q=2) => 6p+9q=6

1(4p - 9q) =>4p - 9q= -1

10p=5 => p=5/10=1/2

q={4(1/2)+1}/9

q=3/9=1/3

from these values 1/√x =p=1/2 =>√x=2 =>x=4

1/√y=q=1/3 =>√y=3 =>y=9

x=4 and y=9
