What is the answer to |3x| = 9? I may be asking more questions like this within the next few minutes or so because I don't get this very well ...

Well, the variable could be positive or negative. The answer could be 3 or - 3. This is because absolute value looks at how far away each number is away from zero. - 3 is three spaces away from zero and 3 is also 3 spaces away from zero.

The answer is x = - 3
