Answer:
x=2
y=3
Solution:
First we find common denominators. It is "xy". Then we multiply numerators by common denominator. We get followings:
(4y-3x)/xy=1; (6y+15x)/xy=8
Then
4y-3x=xy;
6y+15=8xy
Multiply first equasion by 5
20y-15x=5xy
Now we add two equasions to get one
20y-15x=5xy
6y+15x=8xy
We get 
26y=13xy
Cut "y" and we will find "x"
26=13x
x=2
Put x value into the first equasion(4y-3x=xy) to find out "y"
4y-6=2y
2y=6
y=3
 
        
             
        
        
        
Choice 1. f(5)=5-3 which equals 2
        
             
        
        
        
Divide both.
82/8=10.25
37/4=9.25
The first is greater.
        
             
        
        
        
Answer:
Answer is 2a + 8 because 2 times a is 2a and 2 times 4 is 8
