I really just don't get them. They hardly explained anything in the lesson. For instance:

a+1/2 + 3/2 = 1/a
They use the quadratic formula to solve it.
But in:
x/5 - 4/5 = 1/x
They dont.

I guess I'm just generally confused about it. If any of you can explain the steps and conditions in more detail Id appreciate it :)
