Answer:
x =1/5 ,y =-2
Step-by-step explanation:
5/x +6y =13-------------1
3/x +4y =7----------------2
multiplying 2 with equ.1 and 3with equ.2 we get,
10/x +12y =26-------------1
9/x +12y =21--------------2
subtracting equ. 2 from equ. 1 we get.
10/x -9/x =26-21
or, 1/x =5
or, x=1/5 .
putting value of x in equ. 2
15+4y =7
or, 4y=-8
or, y=-2
