I got this question wrong and I do not understand why. lx3l = 5 x = 8. Since the x is in the absolute value bars, I replaced it with 8 which gave me 83 which does equal 5. Where did I go wrong here?

Best ResponseYou've already chosen the best response.0It was a True or False Question. It says "One solution of: lx3l = 5 is x = 8"

Best ResponseYou've already chosen the best response.0I replaced x with 8 so the problem read l83l = 5. Since the 83 was in absolute value bars, I read it as 83 which equals 5.

Best ResponseYou've already chosen the best response.0you did good to begine with; but what the absolute value bars are telling us is the the "equation" inside of them...that value will always become positive. What does 83= ? then ?

Best ResponseYou've already chosen the best response.0a  minus a + is is actually a negative plus a negative, so it would be 11. Okay, I get that, but what I do not get is I thought absolute value bars mean to ignore any positive or negative signs and read the number for exactly what it's value is UNLESS there is a sign outside of the bars, for example, if it was l83l.

Best ResponseYou've already chosen the best response.0your are correct in your understanding of the absolute value bars, but what you are missing is that those bars only apply to the "value" inside of them and not to any of the individual parts that make up that value. since 83 = 11 then 83 = 11 = 11. Does that make sense?

Best ResponseYou've already chosen the best response.0It does. I did not realize the bars only applied to the value and not to any negative sign. I get it now, thank you very much!
