Divide both.
82/8=10.25
37/4=9.25
The first is greater.
        
             
        
        
        
The answer to your problem is 50b+8
 
        
        
        
-3(y-5) = 24...distribute through the parenthesis
-3y + 15 = 24....subtract 15 from both sides
-3y = 24 - 15
-3y = 9...divide both sides by -3
y = 9/-3
y = -3
        
             
        
        
        
This is known as the commutative property of addition. 
Hope this helps!
