Answer:
 {y,x} = {-6,-2} 
Step-by-step explanation:
/ Solve equation [2] for the variable  y  
 
  [2]    y = 2x - 2
// Plug this in for variable  y  in equation [1]
   [1]    (2x-2) - x = -4
   [1]    x = -2
// Solve equation [1] for the variable  x  
   [1]    x = - 2 
// By now we know this much :
    y = 2x-2
    x = -2
// Use the  x  value to solve for  y  
    y = 2(-2)-2 = -6 
 
        
             
        
        
        
Answer: x=133
Step-by-step explanation:
This is a hexagon that has a total of 720 degrees (which you can get by the formula of degrees = (# of sides – 2) * 180). 
You first add up all your side: 
150+130+97+120+90 +x = 587 + x
587+x = 720
x=133
 
        
             
        
        
        
last one is the solution u should choose
 
        
                    
             
        
        
        
Y = 12x is a direct variation which is a proportion.
As x increases y also increases.
