Add the fractions on the left and you get 5/k.
Now you have 5/k = 3/5.
Cross multiply: 25 = 3k, or k = 25/3

because if 2+3=5 then of course 2/k + 3/k would equal 3/5 because u take the big number of the math question and the answer together in this case 3/k is big and the answer to 2k plus 3k is 5 put them together and u have 3/5

2/k+3/k=3/5
2+3/k =3/5
5/k =3/5
3k =25
k =25/3
therefore wen u replace k in 2/k+3/k... u will get 3/5

2/k + 3/k = 3/5
(2+3)/k=3/5
(2+3)=3K/5
5=3k/5
25=3k
25/3=k

(2/k) + (3/k) = (3/5)
multiply everything by 5k
10 + 15 = 3k
25 = 3k
k = (25/3)

its true if k = 25/3
