I need help

Answer 2

Step-by-step explanation:

2/x+3/y=13

(2y+3x)/xy=13

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

5/x-4/y=-2

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

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

(2)×3 +(1)×4

-12x+15y=-6xy

12x+8y =52xy

____________

23y=46xy

46xy=23y

x=23y/46y

x=1/2

substituting X value in (1)

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

3/2=(13/2)y-2y

3/2=(13-4/2)y

3/2=9/2y

y=3/9

y=1/3

x+y=1/2+1/3

=3+2/6

=5/6

hope it was helpful
