12x - 14 = 5x12x = 5x + 147x = 14x = 2
Well, darling, the Least Common Multiple (LCM) of 4x and 5x is simply 20x. You see, 4x and 5x are both factors of 20x, making it the smallest multiple they both share. So, there you have it, sweet pea, 20x is the LCM of those two little troublemakers.
If you're adding them, that equals 12x
you factor out the common 5so it would be: 5(x + 2)so that when you multiply back out 5 by x you get 5x and 5 by 2 you get 10
