    lol, no you moved 12x to the left and it became -12x, good. Now youve moved 9 from the left and got it to the right, so it'll be -9 :) 13x-12x = -3-9

    hence, when we have the same signs (-) (-) = we add, (+) (+) = add, but if we had (-) and (+) = we subtract and the number takes the sign of the bigger number :)
