[ 1/1 Equation]
    Work: Find the solution of equation 40(1-x)2 = 32.4 .
    Question type: Equation
    Solution:Original question:
     40(1 x ) × 2 =
162
5
     Left side of the equation = 80(1 x )
    The equation is transformed into :
     80(1 x ) =
162
5
    Remove the bracket on the left of the equation:
     Left side of the equation = 80 × 180 x
                                             = 8080 x
    The equation is transformed into :
     8080 x =
162
5

    Transposition :
      - 80 x =
162
5
80

    Combine the items on the right of the equation:
      - 80 x = -
238
5

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
238
5
= 80 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 :
     80 x =
238
5

    The coefficient of the unknown number is reduced to 1 :
      x =
238
5
÷ 80
        =
238

80
        =
119

40

    We obtained :
      x =
119
200
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.595
