Question

1/x + 1/y =2
1/y - 1/x =6

Please solve using elimination method

Answer 1

Step-by-step explanation:

1/x + 1/y = 2 => equation 1

1/y - 1/x = 6 => equation 2

let 1/x = u and 1/y = v , then

u + v = 2 => equation 3

v - u = 6 => equation 4

u = 2 - v => equation 5

using 5 in 3 , we get

v - 2 - v = 6

-2 = 6

Answer 2

ANSWER

x=1/4 and y=-1/2
