[ 1/1 Equation]
    Work: Find the solution of equation (8950+20+X)*3.9% = 4X .
    Question type: Equation
    Solution:Original question:
     (8950 + 20 + X ) ×
39
1000
= 4 X
    Remove the bracket on the left of the equation:
     Left side of the equation = 8950 ×
39
1000
+ 20 ×
39
1000
+ X ×
39
1000
                                             =
6981
20
+
39
50
+ X ×
39
1000
                                             =
34983
100
+
39
1000
X
    The equation is transformed into :
     
34983
100
+
39
1000
X = 4 X

    Transposition :
     
39
1000
X 4 X = -
34983
100

    Combine the items on the left of the equation:
      -
3961
1000
X = -
34983
100

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
34983
100
=
3961
1000
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 :
     
3961
1000
X =
34983
100

    The coefficient of the unknown number is reduced to 1 :
      X =
34983
100
÷
3961
1000
        =
34983
100
×
1000
3961
        = 34983 ×
10
3961

    We obtained :
      X =
349830
3961
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 88.318606
