    Work: Find the solution of equation （4500×12×0.9-60%×70X×6.95%）÷（40%×70X+50%×70X） = 3.8% .
    Question type: Equation
    Solution:Original question:
     (4500 × 12 ×
9
10
 −
60
100
 × 70 X ×
139
2000
) ÷ (
40
100
 × 70 X +
50
100
 × 70 X ) =
19
500
     Multiply both sides of the equation by:(
40
100
 × 70 X +
50
100
 × 70 X )
     (4500 × 12 ×
9
10
 −
60
100
 × 70 X ×

 × 70 X )
    Remove a bracket on the left of the equation:：
     4500 × 12 ×

    Remove a bracket on the right of the equation:：
     4500 × 12 ×

    The equation is reduced to :
     48600 −
2919
1000
 X =
133
125
 X +
133
100
 X
    The equation is reduced to :
     48600 −
2919
1000
 X =
1197
500
 X

    Transposition :
      -
2919
1000
 X −
1197
500
 X = - 48600

    Combine the items on the left of the equation:
      -
5313
1000
 X = - 48600

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     48600 =
5313
1000
 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 :
     
5313
1000
 X = 48600

    The coefficient of the unknown number is reduced to 1 :
      X = 48600 ÷
5313
1000
        = 48600 ×
1000
5313
        = 16200 ×
1000
1771

    We obtained :
      X =
16200000
1771
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 9147.374365
