Respuesta :

Answer:

{y,x} = {12,1}

Step-by-step explanation:

Solve equation [2] for the variable  y  

 [2]    y = 12x

Plug this in for variable  y  in equation [1]

  [1]    (12x) - x = 11

  [1]    11x = 11

Solve equation [1] for the variable  x  

  [1]    11x = 11

  [1]    x = 1

By now we know this much :

   y = 12x

   x = 1

Use the  x  value to solve for  y  

   y = 12(1) = 12
