Answer:
C. Add the equations
Step-by-step explanation:
 Adding both the equations will help eliminating 5y.
 
        
             
        
        
        
I just took the 16 chairs and added 2 since thats how many are left over, then since adding these 16 chairs, you are creating 2 more rows, so (16+2)/2 =9 Therefore, each row must have nine chairs in it and Hue starts off with 5x9+2= 47 chairs
        
             
        
        
        
Answer:
C) (x,y) → (x,y+6)
Step-by-step explanation:
As the x value stays the same after the transformation, we know that there can be no changes to the value x, automatically limiting the options to answer C.
The mathematical way to find the value y is changed by would be by setting up a small equation as follows:
 , where n is some number that the y value is altered by.
, where n is some number that the y value is altered by.
Solving for n gives the value 6, proving that the translation must add 6 to the y value.
