Answer:

x=1/2,y=1/3

Step-by-step explanation:

2/x + 3/y=13..…......(1)

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

(15 - (2)×2

10/x+15/y =65

10/x - 8/y = -4

(-)15/y - (-8/y)=65-(-4)

or, 23/y=69

or, y=23/69=1/3

then,put the value of y on equation number (1)

2/x + 3÷1/3=13

or,2/x+9=13

or,2/x=13-9

or, x=2/4

or, x=1/2. [ANS]
