Question

1/x+1/y=8,4/x-2/y=2​

Answer 1

Answer:

x = 1/3

y = 3/23

Step-by-step explanation:

1/x + 1/y = 8      --- eq 1

4/x -2/y = 2      --- eq 2

taking 2 common from both sides of eq 2  we have,

2/x - 1/y = 1

so now the two eq are as follows

1/x + 1/y = 8

2/x  - 1/y = 1

adding them we get,

1/x + 2/x = 9

3/x = 9

x = 3/9

x = 1/3

substituting value of x in eq 1 we get,

1/3 + 1/y = 8

1/y = 8 - 1/3

1/y = 23/3

y = 3/23

Ans)  x= 1/3, y = 3/23
