Question

2/x+3/y=13 and 5/x-4/y=2 solve the pair of linear eq​uation

Answer 1

Answer:

let's 1/x=a

1/y=b

2a+3b=13

5a-4b=2

equation (i)×4 & (ii)×3

8a+12b=52

15a-12b=6

23a=58

a=58/23

put equation (i)

2a+3b=13

2×58/23+3b=13

3b=13-116/23

3b=183/23

b=183/23×1/3

b=61/23

put the a&b value of x

1/x=a

1/x=58/23

58x=23

x=23/58

1/y=b

1/y =61/23

61x=23

x=23/61

now,x=23/58… y=23/61
