[ 1/1 Equation]
    Work: Find the solution of equation (1.3621-0.00406V)60 = (30%V-28)+20 .
    Question type: Equation
    Solution:Original question:
     (
13621
10000
203
50000
V ) × 60 = (
30
100
V 28) + 20
    Remove the bracket on the left of the equation:
     Left side of the equation =
13621
10000
× 60
203
50000
V × 60
                                             =
40863
500
609
2500
V
    The equation is transformed into :
     
40863
500
609
2500
V = (
30
100
V 28) + 20
    Remove the bracket on the right of the equation:
     Right side of the equation =
30
100
V 28 + 20
                                               =
30
100
V 8
    The equation is transformed into :
     
40863
500
609
2500
V =
30
100
V 8

    Transposition :
      -
609
2500
V
30
100
V = - 8
40863
500

    Combine the items on the left of the equation:
      -
1359
2500
V = - 8
40863
500

    Combine the items on the right of the equation:
      -
1359
2500
V = -
44863
500

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
44863
500
=
1359
2500
V

    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 :
     
1359
2500
V =
44863
500

    The coefficient of the unknown number is reduced to 1 :
      V =
44863
500
÷
1359
2500
        =
44863
500
×
2500
1359
        = 44863 ×
5
1359

    We obtained :
      V =
224315
1359
    This is the solution of the equation.

    Convert the result to decimal form :
      V = 165.058867
