Answer:
The first 2 and the last one
Step-by-step explanation:
You need to have an input per output, and to choose one or multiple the need to have a continuous pattern. Ex.+5 ad -2 on both sides every time would be a linear function.  
 
        
             
        
        
        
The answer is 2 first you add then multiple
        
                    
             
        
        
        
<span>Simplifying
2x + n = 3
 
Reorder the terms:
n + 2x = 3
 Solving
n + 2x = 3
 
Solving for variable 'n'.
  
Move all terms containing n to the left, all other terms to the right.
 
Add '-2x' to each side of the equation.
n + 2x + -2x = 3 + -2x
 
Combine like terms: 2x + -2x = 0
n + 0 = 3 + -2x
n = 3 + -2x
 
Simplifying
n = 3 + -2x</span>
        
             
        
        
        
6/12 and 4/8 are equal fractions, as, when simplified, they share a simplified fraction. 
Note that what you do to the denominator, you do to the numerator. Find common denominators for both fractions: 
(4/8)/(2/2) = 2/4
(6/12)/(3/3) = 2/4
As you can tell, when they share a common denominator (4), the numerators are the same as well (3).
