You need to know 3 things to solve Example 1:
- Absolute value is how the number or expression is from zero. In other words, | x | = x.
- You also need to plug in the numbers in for their corresponding variables.
- You also need to distribute the numbers before the absolute value bars, and when you distribute, you don't get rid of the absolute value bars.
P.S.: These are absolute value bars → ║.
