How do you solve |-4x|/(3-x)<0 ?
- QuoiLv 79 years agoFavorite Answer
As the LHS side is negative, the numerator and denominator must be of different signs.
There are two scenarios thus:
1) Abs(-4x) is negative, 3-x is postive
2) Abs-4x is positive, 3-x is negative
As the abs function is always positive, then 3-x must always be negative
