Question

Solve:
|x| = 5


{5}

{-5}

{-5, 5}

{-1, 5}

Answer 1

|x| means the absolute value of x, so even if it is negative, it becomes positive. Knowing this, you will have two numbers, which narrows it down to C and D. If X = 5, then X can be both negative and positive 5, meaning that your answer is C.
