Question

2 byx + 3by y equal to13 and 5 by x - 4 by y equal to-2​

Answer 1

Answer:

x=1/2, y=1/3

Step-by-step explanation:

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

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

(1)*4+(2)*3

8/x + 12/y = 52

15/x - 12/y = -6

adding we get

23/x = 46

this gives

x= 1/2

puttin value of x in (1)

3/y = 13- 4

3/y = 9

y = 1/3
