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
