5/a-5+3/5-a=0
5/a-5=a-3/5
5/a-a=5-3/5
5/a-a=22/5
5(1/a-a/5)=22/5
It is a trinomial with negative Î. So there are no actual prices for a.

3/5-a = -3/a-5,
so 5/a-5 -3/a-5 = 2/a-5, since we have common denominators,
so you are correct! Well done.

5/a-5+3/5-a=?
5-5a+(3/5)a-1=?a
4-(22/5)a=?a
4a-22/5=?
so, 5/a-5+3/5-a=4a-22/5
