    Work: Find the solution of equation (5000×12×0.9-70%×124X×6.4%)÷(30%×124X+5%×124X) = 3.8% .
    Question type: Equation
    Solution:Original question:
     (5000 × 12 ×
9
10
70
100
× 124 X ×
32
500
) ÷ (
30
100
× 124 X +
5
100
× 124 X ) =
19
500
     Multiply both sides of the equation by:(
30
100
× 124 X +
5
100
× 124 X )
     (5000 × 12 ×
9
10
70
100
× 124 X ×
32
500
) =
19
500
(

100
× 124 X )
    Remove a bracket on the left of the equation::

× 124 X )
    Remove a bracket on the right of the equation::
     5000 × 12 ×

    The equation is reduced to :
     54000
3472
625
X =
1767
1250
X +
589
2500
X
    The equation is reduced to :
     54000
3472
625
X =
4123
2500
X

    Transposition :
      -
3472
625
X
4123
2500
X = - 54000

    Combine the items on the left of the equation:
      -
18011
2500
X = - 54000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     54000 =
18011
2500
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 :
     
18011
2500
X = 54000

    The coefficient of the unknown number is reduced to 1 :
      X = 54000 ÷
18011
2500
        = 54000 ×
2500
18011

    We obtained :
      X =
135000000
18011
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 7495.419466
