Question

2\x+3\y=13 5\x+4\y=-2​

Answer 1

Answer:

Explanation

let 1/x=x, 1/y=y

2x+3y=13.................(1)

5x+4y=-2...................(2)

multiplying by 4 in (1) and multiplying by 3 in (2)

subtracting (2) to(1)

15x+12y=-6

8x+12y=52

-      -        -

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

7x=-42

x=-6

put the value of x in equation (2)

-30+4y=-2

4y=28

y=7

1/x= -1/6

i/y= 1/7
