[ 1/1 Equation]
    Work: Find the solution of equation (X-2000)*80% = 375000 .
    Question type: Equation
    Solution:Original question:
     ( X − 2000) ×
80
100
 = 375000
    Remove the bracket on the left of the equation:
     Left side of the equation = X ×
80
100
 − 2000 ×
80
100
                                             = X ×
80
100
 − 1600
    The equation is transformed into :
     
80
100
 X − 1600 = 375000

    Transposition :
     
80
100
 X = 375000 + 1600

    Combine the items on the right of the equation:
     
80
100
 X = 376600

    The coefficient of the unknown number is reduced to 1 :
      X = 376600 ÷
80
100
        = 376600 ×
100
80
        = 9415 ×
100
2

    We obtained :
      X =
941500
2
    This is the solution of the equation.

    By reducing fraction, we can get:
      X = 470750
