    Work: Find the solution of equation (1050×12-70%×60X×9%）÷（30%×60X+2%×60X） = 3.84% .
    Question type: Equation
    Solution:Original question:
     (1050 × 12 −
70
100
 × 60 X ×
9
100
) ÷ (
30
100
 × 60 X +
2
100
 × 60 X ) =
96
2500
     Multiply both sides of the equation by:(
30
100
 × 60 X +
2
100
 × 60 X )
     (1050 × 12 −
70
100
 × 60 X ×
9
100
) =
96
2500
(
30
100
 × 60 X +

100
 × 60 X )
    Remove a bracket on the left of the equation:：
     1050 × 12 −
70
100
 × 60 X ×
9
100
 =
96
2500
(
30
100
 × 60 X +
2
100
 × 60 X )
    Remove a bracket on the right of the equation:：
     1050 × 12 −
70
100
 × 60 X ×
9
100
 =
96

    The equation is reduced to :
     12600 −
189
50
 X =
432
625
 X +
144
3125
 X
    The equation is reduced to :
     12600 −
189
50
 X =
2304
3125
 X

    Transposition :
      -
189
50
 X −
2304
3125
 X = - 12600

    Combine the items on the left of the equation:
      -
28233
6250
 X = - 12600

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     12600 =
28233
6250
 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 :
     
28233
6250
 X = 12600

    The coefficient of the unknown number is reduced to 1 :
      X = 12600 ÷
28233
6250
        = 12600 ×
6250
28233
        = 1400 ×
6250
3137

    We obtained :
      X =
8750000
3137
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 2789.28913
