Answer: x=10 or -2
Step-by-step explanation:
Absolute value is the distance from 0 and a distance can't be negative, so the absolute value of any number is positive. Thus, inside the absolute value
(|a +b|) of a positive result can either be positive or negative. For this reason, we need to set up two equations, one for positive solution, one for negative solution.
- By means, if | a + b | =3, a+b can be either negative or positive, but the answer will always be positive 3.
|x-4|=6
x-4=6 or x-4=-6
x=10 x=-2
