Answer:

{x,y} = {6,-4}  

 

System of Linear Equations entered :

 [1]           5x-7y=58

 [2]           y=-x+2

Equations Simplified or Rearranged :

  [1]    5x - 7y = 58

  [2]    x + y = 2

Graphic Representation of the Equations :

   -7y + 5x = 58        y + x = 2  

 

 

Solve by Substitution :

// Solve equation [2] for the variable  y  

 

 [2]    y = -x + 2

// Plug this in for variable  y  in equation [1]

  [1]    5x - 7•(-x +2) = 58

  [1]    12x = 72

// Solve equation [1] for the variable  x  

  [1]    12x = 72  

  [1]    x = 6  

// By now we know this much :

   x = 6

   y = -x+2

// Use the  x  value to solve for  y  

   y = -(6)+2 = -4  

Solution :

{x,y} = {6,-4}
