To find the interval for the first piece, find where the inside of the absolute value is non-negative.
Subtract from both sides of the inequality.
In the piece where is non-negative, remove the absolute value.
To find the interval for the second piece, find where the inside of the absolute value is negative.
Subtract from both sides of the inequality.
