Question

2÷ X +5÷y =1 and 60÷ X + 40÷ y = 19 by cross multiplication method

Answer 1

here is the ans

x=4 y=10

Answer 2

2/x+5/y=1...........a

2y+5x=xy.............1

60/x+40/y=19

19xy=60y+40x

from 1

19(5x+

2y)=60y+40x

95x+38y=60y+40x

55x=22y

y=5/2x.........b

putting value of y in a eq.

we get x=4

now putting x in eq b

we get your=10
