I mean. if I add 4 to both numerators and denominators of the first

It most certainly will. Is 1/2 equal to (1+4)/(2+4)?

Gary, do you make any attempt yourself to answer questions such as
this before posting them?

yes, every one of them with out a fail. but I ofter fail to see the
trick part, i.e in this question the trick was to let x = x-a where a
is the value to adjust to make the question look easier to handle for
further steps.

You asked:

"if I add 4 to both numerators and denominators of the first term on
the RHS, that will not change its value or will it."

So you are wondering if adding the same quantity to both numerator and
denominator of a fraction will change its value. Did you try an
example? For example, as another poster suggested, did you try
something like:

1/2 =? (1 + 4) / (2 + 4)

to see if it might be false? The reason I asked you is that almost any
example you might have tried would have shown you the answer to that
question, leading me to believe that you didn't try very hard to check
it on your own.
