[ 1/1 Equation]
    Work: Find the solution of equation （2100*12*90%-70%*110X*6.31%）/(30%*110X+5%*110X) = 3.8% .
    Question type: Equation
    Solution:Original question:
     (2100 × 12 ×
90
100
 −
70
100
 × 110 X ×
631
10000
) ÷ (
30
100
 × 110 X +
5
100
 × 110 X ) =
19
500
     Multiply both sides of the equation by:(
30
100
 × 110 X +
5
100
 × 110 X )
     (2100 × 12 ×
90
100
 −
70
100
 × 110 X ×
631
10000
) =
19
500
(
30
100
 × 110 X +
5
100
 × 110 X )
    Remove a bracket on the left of the equation:：
     2100 × 12 ×
90
100
 −
70
100
 × 110 X ×
631
10000
 =
19
500
(
30
100
 × 110 X +
5
100
 × 110 X )
    Remove a bracket on the right of the equation:：
     2100 × 12 ×
90
100
 −
70
100
 × 110 X ×
631
10000
 =

500
 ×
30
100
 × 110 X +
19
500
 ×
5
100
 × 110 X
    The equation is reduced to :
     22680 −
48587
10000
 X =
627
500
 X +
209
1000
 X
    The equation is reduced to :
     22680 −
48587
10000
 X =
1463
1000
 X

    Transposition :
      -
48587
10000
 X −
1463
1000
 X = - 22680

    Combine the items on the left of the equation:
      -
63217
10000
 X = - 22680

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     22680 =
63217
10000
 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 :
     
63217
10000
 X = 22680

    The coefficient of the unknown number is reduced to 1 :
      X = 22680 ÷
63217
10000
        = 22680 ×
10000
63217
        = 3240 ×
10000
9031

    We obtained :
      X =
32400000
9031
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 3587.642565
