Question

Solve: |x + 3| = 3
Answer

{0, 6}

{0, -6}

{-6, 6}

{-6}

Answer 1

You have to solve this by putting the 3 as negative and positive.
Here is an example:

|x-4|=6

x-4=6 x-4=-6
x=10 x=-2

Get it?

Answer 2

No.

Answer 3

You have to do two cases when you have absolute values.
Case 1 look just like the original problem but without the absolute value.

x+3=3
x=3-3=?

Case 2 is where the number on the right changes negative
x+3=-3
x=-3-3=?
