Distribute -3 to the rest of the numbers by multiplying them together. That’s all you need to do you don’t have to solve
        
                    
             
        
        
        
Answer:
Hi There the correct answer is {x,y} = {-1,-10}  
  
System of Linear Equations entered :
   [1]    3x - y = 7
   [2]    4x - 2y = 16
Graphic Representation of the Equations :
    y + 3x = 7        -2y + 4x = 16  
  
  
Solve by Substitution :
// Solve equation [1] for the variable  y  
  
  [1]    y = 3x - 7
// Plug this in for variable  y  in equation [2]
   [2]    4x - 2•(3x-7) = 16
   [2]    -2x = 2
// Solve equation [2] for the variable  x  
   [2]    2x = - 2  
   [2]    x = - 1  
// By now we know this much :
    x = -1
    y = 3x-7
// Use the  x  value to solve for  y  
    y = 3(-1)-7 = -10  
Solution :
 {x,y} = {-1,-10}  
Hope it helps!
