  • Solve equation for the variable  y  

   [2]    y = 3x + 6


  •  Plug this in for variable  y  in equation

   [1]    (3x+6) - 4x = -1


  [1]     - x = -7


  • Solve equation for the variable  x  

    [1]    x = 7  

  • By now we know this much :

     y = 3x+6


    x= 7

  • Use the  x  value to solve for  y  

    y = 3(7)+6 = 27  

  • Solution :

  {y,x} = {27,7}  


Hope this helps!

Have an amazing day :)
