5
x = - 138610000

    Combine the items on the right of the equation:
      -
207
5
x = - 11386

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     11386 =
207
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 :
     
207
5
x = 11386

    The coefficient of the unknown number is reduced to 1 :
      x = 11386 ÷
207
5
        = 11386 ×
5
207

    We obtained :
      x =
56930
207
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 275.024155
