Assume it's
:

:
; Added to both sides
:
They have the same denominators so we can just write it:
= ; combine like terms, we have quadratic now
That will factor to:

Cancel out the (a+2)'s and we have a simple equation
a - 1 = 3
:
a = 3 + 1
:
a = 4
:
:
Check solution in the original equation, substitute 4 for a

3 is equal to 18/6:
; confirms our solution of a = 4

Could you follow what we did here? Any questions?
