Best ResponseYou've already chosen the best response.1alright, this one is a bit trickier first, let's add 4 to each side to get the absolute value by itself x10 = 2x + 4 now we write two equations: x  10 = 2x + 4 x  10 = (2x+4) solve both for x. you will get 2 different values

Best ResponseYou've already chosen the best response.1good, now plug both back into the original equation. only one ends up working in the end

Best ResponseYou've already chosen the best response.0wait absolute value means that the  is actually positive unless written like this 10

Best ResponseYou've already chosen the best response.1good, x = 2 is our answer. x = 14 is an extraneous solution

Best ResponseYou've already chosen the best response.0everything that is enclosed in an absolute bars   equals to zero an unknown number with variable x may either be positive or negative x = x and x = x this is why we have two sets of answers for the most part

Best ResponseYou've already chosen the best response.1or, to do it algebraically: x  10 = (2x+4) x  10 = 2x  4 3x = 6 x = 2

Best ResponseYou've already chosen the best response.0in this case wouldnt it be x+10 and x+(10) be the same or no and why?

Best ResponseYou've already chosen the best response.1x = 3 doesn't work, try plugging it back into the original equation

Best ResponseYou've already chosen the best response.1no, x+10 and x+(10) are not the same
