Question

1/x+y +1/x-y =7, 1/x+y - 1/x-y =1​

Answer 1

Answer:

see below

Step-by-step explanation:

1+y(1−x)(1−y2)+x2(y+x)(1−x)(y2−x2)−y2(y+1)(y2−1)(x−y)

Answer 2

Answer:

The solution is x = 7/24 and y = -1/24

Step-by-step explanation:



1/x+y +1/x-y =7 ---------(1)

1/x+y - 1/x-y =1​ ---------(2)

From (1)+(2), we get,

2/(x+y) = 8 => 1/(x+y) = 4 => x+y = 1/4 --------(3)

And from (1)-(2) , we get,

2/(x-y) = 6 => 1/(x-y) = 3 => x-y = 1/3 ---------(4)

Now, from (3)+(4) , we get,

2x = 1/3 + 1/4 => 2x = 7/12 => x = 7/24

Putting x = 7/24 in equation (3) , we get ,

7/24 + y = 1/4 => y = 1/4 - 7/24 = -1/24

Hence, x = 7/24 and y = -1/24
