Answer:
They can`t cross because the slopes are the same.
Since the first equation isn`t simplified, I`ll simplify it.
-x + 4y = -8
4y = x - 8
<u>y = x - 2</u>
After both are simplified, both slopes will be positive 1x. That means the lines are parallel and never cross. I`m sorry if this wasn`t much help, but that is the only answer I can think of. If there is not other option than placing a real answer, than I wouldn`t know how to solve this, sorry.

Answer:
The fraction of the students who failed to went partying = 
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied
No. of students partied before the exam = 20 % of total students
⇒ No. of students partied before the exam =
× 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam = 
Thus the fraction of the students who failed to went partying =
