Question

3/x -1/y = -9 ; 3/x + 3/y =5​

Answer 1

Answer:

3/x-1/y=-9_____(1)

3/x+3/y=5______(2)

- - -

_________

-1/y-3/y=-14

y= 2/7

from equation (1)

x=-6/11

Answer 2

Answer:

x = -6/11, y = 2/7

Step-by-step explanation:

Given :

(3/x) - (1/y) = -9    ----- (1)

(3/x) + (3/y) = 5   ----- (2)

Let (1/x) = a, (1/y) = b

Then the equations will become,

3a - b = -9

3a + 3b = 5

--------------------

      -4b = -14

        b = 7/2

Then,

y = (2/7)

Now,

Place b = 7/2 in above equation, we get

3a + 3b = 5

=> 3a + 3(7/2) = 5

=> 6a + 21 = 10

=>  a = -11/6

Then,

x = -6/11

Therefore,

x = -6/11, y = 2/7
