    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
52
5
=
49
5
x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
49

49

    We obtained :
      x =
52
49
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1.061224
