Absolute value represents distance. Distances can't be negative.
So it's impossible to have |3-w| be some negative value.
Which is why

has no solutions
The issue with using the side-splitter to solve for x is that the side-splitter theorem is used to find lengths of the sides being split by parallel lines. In this case, the x is on a line that is parallel and thus could not be solved for using this theorem.
If we created a triangle where the tops of the non-parallel lines connected, we would be able to compare the following and solve:

However, none of this would help us solve for x using this theorem.
Answer:
15
Step-by-step explanation:
If y is 20 when x is 5 then x is always 1/4 of y
60*(1/4)=15
Answer:
3 miles
Step-by-step explanation:
1.7 carry a one because 3+7 is 10
