Question

3/x-1/y=-9 और 2/x+3/y=5 के हल में x का मान हैं।​

Answer 1

Answer:

let 1/x=a and 1/y=b

then equation become

3a -b=-9.......(i)

2a + 3b = 5.........(ii)

multiply eq. (i) by 3 and add eq (ii)

9a -3b = -27.......(i)

2a +3b = 5.......(ii)

________________

11a = -22

a= -2

put in eq. (i)

we get 3(-2) -b = -9

-6 -b = -9

-b = -9+6

b=3

Now as 1/x = a then x=1/a = -1/2

and 1/y = b then y= 1/b = 1/3
