Question

2/x+3/y=13 and 5/
x-4/y=-2 then the solution is

Answer 1

Step-by-step explanation:

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

5y-4x= -2xy. eqn(2)

multiply 4 in eqn 1 and 3 in eqn 2

8y+12x = 52xy

15y-12x = -6xy

add both eqn 1 and 2

23y = 46xy

x=1/2

2y+3/2=13y/2

2y-13y/2= -3/2

4y-13y=-3

-9y= -3

y=1/3
