    Work: Find the solution of equation {5000*12*0.9-70%*186X*4.5%}/{30%*186X+5%*186X} = 3.8% .
    Question type: Equation
    Solution:Original question:
     (5000 × 12 ×
9
10
 −
70
100
 × 186 X ×
9
200
) ÷ (
30
100
 × 186 X +
5
100
 × 186 X ) =
19
500
     Multiply both sides of the equation by:(
30
100
 × 186 X +
5
100
 × 186 X )
     (5000 × 12 ×
9
10
 −
70
100
 × 186 X ×

100
 × 186 X )
    Remove a bracket on the left of the equation:：
     5000 × 12 ×

    Remove a bracket on the right of the equation:：
     5000 × 12 ×

    The equation is reduced to :
     54000 −
5859
1000
 X =
5301
2500
 X +
1767
5000
 X
    The equation is reduced to :
     54000 −
5859
1000
 X =
12369
5000
 X

    Transposition :
      -
5859
1000
 X −
12369
5000
 X = - 54000

    Combine the items on the left of the equation:
      -
5208
625
 X = - 54000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     54000 =
5208
625
 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 :
     
5208
625
 X = 54000

    The coefficient of the unknown number is reduced to 1 :
      X = 54000 ÷
5208
625
        = 54000 ×
625
5208
        = 2250 ×
625
217

    We obtained :
      X =
1406250
217
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 6480.414747
