[ 1/1 Equation]
    Work: Find the solution of equation ((X+20)/(1-0.004))*0.004 = 2000 .
    Question type: Equation
    Solution:Original question:
     (( X + 20) ÷ (1 −
1
250
)) ×
1
250
 = 2000
    Remove a bracket on the left of the equation:：
     ( X + 20) ÷ (1 −
1
250
) ×
1
250
 = 2000
     Multiply both sides of the equation by:(1 −
1
250
)
     ( X + 20) ×
1
250
 = 2000(1 −
1
250
)
    Remove a bracket on the left of the equation:
      X ×
1
250
 + 20 ×
1
250
 = 2000(1 −
1
250
)
    Remove a bracket on the right of the equation:：
      X ×
1
250
 + 20 ×
1
250
 = 2000 × 1 − 2000 ×
1
250
    The equation is reduced to :
      X ×
1
250
 +
2
25
 = 2000 − 8
    The equation is reduced to :
     
1
250
 X +
2
25
 = 1992

    Transposition :
     
1
250
 X = 1992 −
2
25

    Combine the items on the right of the equation:
     
1
250
 X =
49798
25

    The coefficient of the unknown number is reduced to 1 :
      X =
49798
25
 ÷
1
250
        =
49798
25
 × 250
        = 49798 × 10

    We obtained :
      X = 497980
    This is the solution of the equation.
