[ 1/1 Equation]
    Work: Find the solution of equation (9980+70+x)*3.2% = 4x .
    Question type: Equation
    Solution:Original question:
     (9980 + 70 + x ) ×
16
500
= 4 x
    Remove the bracket on the left of the equation:
     Left side of the equation = 9980 ×
16
500
+ 70 ×
16
500
+ x ×

    The equation is transformed into :
     
1608
5
+
16
500
x = 4 x

    Transposition :
     
16
500
x 4 x = -
1608
5

    Combine the items on the left of the equation:
      -
496
125
x = -
1608
5

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
1608
5
=
496
125
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 :
     
496
125
x =
1608
5

    The coefficient of the unknown number is reduced to 1 :
      x =
1608
5
÷
496
125
        =
1608
5
×
125
496
        = 201 ×
25
62

    We obtained :
      x =
5025
62
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 81.048387
