    The equation is transformed into :
     ( x 24) ×
3
2800
= ( x 40) ×

    Combine the items on the right of the equation:
      -
3
7000
x = -
6
175

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
6
175
=
3
7000
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 :
     
3
7000
x =
6
175

    The coefficient of the unknown number is reduced to 1 :
      x =
6
175
÷

175
×
7000
3
        = 2 × 40

    We obtained :
      x = 80
    This is the solution of the equation.
