Sagot :

Answer: {y,x} = {-8,-2}                                                                                                    // Solve equation [2] for the variable  y  

 

 [2]    y = x - 6

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

  [1]    (x -6) - 3x = -2

  [1]     - 2x = 4

// Solve equation [1] for the variable  x  

  [1]    2x = - 4  

  [1]    x = - 2  

// By now we know this much :

   y = x-6

   x = -2

// Use the  x  value to solve for  y  

   y = (-2)-6 = -8                                                                                                    Solution :  {y,x} = {-8,-2}
