* =
Factor
* =
Cancel x and (x-3)
* =
which is:
=
cross multiply
nx = 2(x+2) * 3x
nx = (2x + 4) * 3x
nx = 6x^2 + 12x
divide both sides by x
n = (6x + 12)
therefore our equation is:
* =
:
:
:
You can check this out, factor the above
* =
Cancel x, (x-3), and (x+2)
* =
which is
= ; confirms our answer of n = (6x+12)
