|x| = 3
First, break down the problem into these 2 equations: x = 3 and -x = 3
Second, solve the 1st equation: x = 3
Since x = 3 is already solved, there isn't any work.
Third, solve the 2nd equation: -x = 3
Multiply both sides by -1 / Your problem should look like: x = -3
Fourth, collect all of your solutions. / Your problem should look like: x = ±3
Answer: x = ±3 or x = 3, -3
