    Work: Find the solution of equation (5000×12×0.9-70%×115X×6.4%)÷(30%×115X+5%×115X) = 2.7% .
    Question type: Equation
    Solution:Original question:
     (5000 × 12 ×
9
10
70
100
× 115 X ×
32
500
) ÷ (
30
100
× 115 X +
5
100
× 115 X ) =
27
1000
     Multiply both sides of the equation by:(
30
100
× 115 X +
5
100
× 115 X )
     (5000 × 12 ×
9
10
70
100
× 115 X ×
32
500
) =
27
1000
(
30
100
× 115 X +
5
100
× 115 X )
    Remove a bracket on the left of the equation::
     5000 × 12 ×

100
× 115 X )
    Remove a bracket on the right of the equation::
     5000 × 12 ×
9

    The equation is reduced to :
     54000
644
125
X =
1863
2000
X +
621
4000
X
    The equation is reduced to :
     54000
644
125
X =
4347
4000
X

    Transposition :
      -
644
125
X
4347
4000
X = - 54000

    Combine the items on the left of the equation:
      -
4991
800
X = - 54000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     54000 =
4991
800
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 :
     
4991
800
X = 54000

    The coefficient of the unknown number is reduced to 1 :
      X = 54000 ÷
4991
800
        = 54000 ×
800
4991

    We obtained :
      X =
43200000
4991
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 8655.580044
