Answer:
4
Step-by-step explanation:
| x | is an absolute value. This means that the answer will always be positive. Even if x = | -2 | the answer will be 2.
Knowing this, solve it like you would a normal equation.
2x + 1 = 5
2x = 4
x= 2
Because it is an absolute value, both 2 and -2 work. So
| 2 - (-2) |
Subtracting a negative makes it a positive so the answer is
| 4 |
