Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read 
Step-by-step explanation:
Given the equation 
 P=-30h+74
 where p =number of pages left to read and
 h= the number of hours he has spent reading
 Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be 
P=-30h+74
14= -30h + 74
30h= 74-14
 30h= 60
h = 60/30
h =2 hours 
 Ethan will have to spend 2 hours reading if 14 pages are left to read 
 
        
             
        
        
        
Hmm, it looks like it could be commutative property of multiplication. 
The order of the expression is different.
4(2+3)=
4(5)=20
(2+3)4=
(5)4= 20
