    Answer:

      [1]    x – 6y = 3

      [2]    x + 2y = 5

    Graphic Representation of the Equations :

       -6y + x = 3        2y + x = 5  

    Solve by Substitution :

    // Solve equation [2] for the variable  x

     [2]    x = -2y + 5

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

      [1]    (-2y+5) – 6y = 3

      [1]     – 8y = -2

    // Solve equation [1] for the variable  y

      [1]    8y = 2

      [1]    y = 1/4

    // By now we know this much :

       x = -2y+5

       y = 1/4

    // Use the y  value to solve for  x

       x = -2(1/4)+5 = 9/2

    Solution :

    {x,y} = {9/2,1/4}

    Answer:

    33433.2

    Step-by-step explanation:

    504 – 300 = 204

    204 + 800 = 1004

    100 / 3 = 33.3

    1004 x 33.3 = 33433.2
