X + 4y = 7
4x – 3y = 9

Answer

{3,1}

Explaination

3 +4=7[1]    x = -4y + 7

// Plug this in for variable  x  in equation [2]

  [2]    4•(-4y+7) - 3y = 9

  [2]     - 19y = -19

// Solve equation [2] for the variable  y

  [2]    19y = 19

  [2]    y = 1

// By now we know this much :

   x = -4y+7

   y = 1

// Use the  y  value to solve for  x

   x = -4(1)+7 = 3

Solution :

{x,y} = {3,1}
