62
 = 1370

    Transposition :
     
1561

 x = 1370 −
15525
62

    Combine the items on the right of the equation:
     
1561
62
 x =
69415
62

    The coefficient of the unknown number is reduced to 1 :
      x =

    We obtained :
      x =
69415
1561
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 44.46829
