    The equation is transformed into :
     
1953
2500
x + 500 = 12000

    Transposition :
     
1953
2500
x = 12000500

    Combine the items on the right of the equation:
     
1953
2500
x = 11500

    The coefficient of the unknown number is reduced to 1 :
      x = 11500 ÷
1953
2500
        = 11500 ×
2500
1953

    We obtained :
      x =
28750000
1953
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 14720.94214
