Question

Find all numbers x for which |x - 3| = 8

Answer 1

really?

Answer 2

there are harder ones coming after this one

Answer 3

lol

Answer 4

I just want to do a sanity check before I tackle the other ones

Answer 5

you know what you should do?

Answer 6

abs(x-3) = x-3 if x-3 > 0 else -(x-3)

Answer 7

you should ask them to solve both of these
|x-3| <-8
and |x-3|=-8

Answer 8

x-3 = 8
x= 11

and

-(x-3) = 8
-x+3 = 8
x = -5

Answer 9

i bet you a lot of them would get it wrong

Answer 10

lol that is the very next question

Answer 11

i don't know how many times i have told me on here |something| does not have negative output so |f(x)|=-8 has no solution

|f(x)|>0 is never less than 0

Answer 12

so x-3 = 8 or x-3 = -8

so -5 <= x <= 11 is that right?

Answer 13

lol I'm wrong

Answer 14

or you still talking about the equation you gave?

Answer 15

yes

Answer 16

that one guy has it right

Answer 17
