The solution is far too long. Trivial obvious manipulations presented in a long-winded manner make it extremely unpleasant to watch. Teaching math is clearly not your thing. Here is how it is done. If a>3, then 3/a+4/b
It seems that knowing the solutions which are obvious here you invent a backward path as complicated as possible. What bothers me is that you risk making young people sick of mathematics.
A is one and b is two.
Why add 12/5? How did You "get that idea"?
He used equivalency principal to factorise Left hand side
1 + 4 = 5
