melmichigan Posted September 5, 2011 Share Posted September 5, 2011 I am stumped. I cannot figure out why this solution is incorrect. (x-2x-3x-8x) to me becomes x+(-2x)+(-3x)+(-8x) which then is x+(-13x)=-12x. What am I missing, how does the first x become negative? The solution says the answer is -14x. Maybe my brain is fried?
