[ 1/1 Equation]
    Work: Find the solution of equation （1.875-0.00406V）12*5 = （30%V-28）+20 .
    Question type: Equation
    Solution:Original question:
     (
15
8
 −
203
50000
 V ) × 12 × 5 = (
30
100
 V − 28) + 20
     Left side of the equation = (
15
8
 −
203
50000
 V ) × 60
    The equation is transformed into :
     (
15
8
 −
203
50000
 V ) × 60 = (
30
100
 V − 28) + 20
    Remove the bracket on the left of the equation:
     Left side of the equation =
15
8
 × 60 −
203
50000
 V × 60
                                             =
225
2
 −
609
2500
 V
    The equation is transformed into :
     
225
2
 −
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 :
     
225
2
 −
609
2500
 V =
30
100
 V − 8

    Transposition :
      -
609
2500
 V −
30
100
 V = - 8 −
225
2

    Combine the items on the left of the equation:
      -
1359
2500
 V = - 8 −
225
2

    Combine the items on the right of the equation:
      -
1359
2500
 V = -
241
2

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
241
2
 =
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 =
241
2

    The coefficient of the unknown number is reduced to 1 :
      V =
241
2
 ÷
1359
2500
        =
241
2
 ×
2500
1359
        = 241 ×
1250
1359

    We obtained :
      V =
301250
1359
    This is the solution of the equation.

    Convert the result to decimal form :
      V = 221.670346
