Question

2/√x +3y/√y=2 and 4/√x -9/√y=-1

Answer 1

here is your answer by Sujeet,
let to be 1/√x=a
let to be 1/√y=b

then,

2a+3b=2
4a+9b=-1

solve this equation by elimination method,
2a+3b=2*4
4a-9b=-1*2

8a+12b=8
8a-18b=-2
_________
30b=10
b=10/30=1/3


then,
2a+3b=2
2a+3*1/3=2
2a+1=2
2a=2-1
2a=1
a=1/2


Now, putting the value of a and b....
1\√x=1/2
x=√2

then,
1/√y=b
1/√y=1/3
y=√3


that's all....

be happy......

take care....

concentration on your study....
