Answer: The answer should be 3.
Step-by-step explanation: You plug in 2 instead of X and that’s it. Then you calculate your equation, and receive your answer.
 
        
                    
             
        
        
        
Answer:
This is what i get 
Step-by-step explanation:
 
        
                    
             
        
        
        
Y=3x-5
y-3x=-5
Times 2 from both side
y(2)-3x(2)=-5(2)
2y-6x=-10
Times negative from both side
(-)2y-6x(-)=(-)-10
-2y+6x=10
or
6x-2y=10
6x=2y+10
6x-2y=10
Furthermore, we see that both equation have the same 6x-2y=10 which means that both of them have infinity solutions, not a solution. Hope it help!
