Just do it the same way i just told you. When removing the absoulte value you get two cases. 2x+2=14 and 2x+2=14

What you want to do with the second one is to isolate the absolute value. So just add 4 to each side and solve ( 2x+6 = 24 ) it like the first one.

2x + 2 = 14 x means that it is always going to be a positive outcome next look at 14 you know that 14 = 14 but you also know that 14 = 14 so you know that inside the  you have 2x+2 you know that you must get 14 or 14 inside the  once you get 14 or 14 you know that both answers will turn out to be 14 so this means you will get 2 values of x so since 2x+2 can be 14 or 14 you can write two equations 2x+2=14 2x+2=14 now solve for x

isolate x you have 2x+2=14 and 2x+2=14 lets look at 2x+2=14 you want all x terms on one side and all constants on another side so you want to get rid of the +2 on the left side how would you do this?

yes this gives 2x=12 now you want x on it's own you have 2x so what do you do to get x

amorfide Group TitleBest ResponseYou've already chosen the best response.0
yes so your first answer is x=6 now look at 2x+2=14 what must you do to get rid of the +2 then what must you do to get x what do you get?
