[ 1/1 Equation]
    Work: Find the solution of equation (2500*12*0.9-70%*65*X*6.3%)/(30%*65*X*5%*65*X) = 3.8% .
    Question type: Equation
    Solution:Original question:
     (2500 × 12 ×
9
10
70
100
× 65 X ×
63
1000
) ÷ (
30
100
× 65 X ×
5
100
× 65 X ) =
19
500
     Multiply both sides of the equation by:(
30
100
× 65 X ×
5
100
× 65 X )
     (2500 × 12 ×
9
10
70
100
× 65 X ×
63
1000
) =
19
500
(

100
× 65 X )
    Remove a bracket on the left of the equation::
     2500 × 12 ×
9

100
× 65 X ×
63

(
30
100
× 65 X ×
5
100
× 65 X )
    Remove a bracket on the right of the equation::
     2500 × 12 ×
9
10
70
100
× 65 X ×

    The equation is reduced to :
     27000
5733
2000
X =
9633
4000
X X

    After the equation is converted into a general formula, there is a common factor:
    ( √9999X - √110850262 )
    From
        √9999X - √110850262 = 0

    it is concluded that::
        X1=
√110850262
√9999

    Solutions that cannot be obtained by factorization:
        X2≈-106.480999 , keep 6 decimal places
    
    There are 2 solution(s).
