Question

Solve |x| = 5
{-5}
{5}
{-5, 5}

Answer 1

x is in {-5, 5}

Explanation:

The absolute value operator takes away the sign, making the result always positive.

So | -5 | = 5

but also | 5 | = 5

Hence two solutions.

Answer 2

{-5, 5}

Explanation:

|x| = 5

We have both a positive and negative solution

x = 5 and x =-5
