Question

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

Answer 1

Answer:

x=1/2 and y=1/3

Step-by-step explanation:

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

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

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

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

add eqn.(1) and (2)

8y+12x+15y-12x =52xy-6xy

23y=46xy

x= 1/2

put the values of x in eqn(3)

2y+3/2 =13y/2

4y+3=13y

9y=3

y=1/3
