    Work: Find the solution of equation -4082750+300000-450000+A-A*10%/4 = 300000 .
    Question type: Equation
    Solution:Original question:
      - 4082750 + 300000 − 450000 + A − A ×
10
100
 ÷ 4 = 300000
     Left side of the equation = - 4082750 + 300000 − 450000 + A − A ×
1
40
                                             = - 4232750 +
39
40
 A
    The equation is transformed into :
      - 4232750 +
39
40
 A = 300000

    Transposition :
     
39
40
 A = 300000 + 4232750

    Combine the items on the right of the equation:
     
39
40
 A = 4532750

    The coefficient of the unknown number is reduced to 1 :
      A = 4532750 ÷
39
40
        = 4532750 ×
40
39

    We obtained :
      A =
181310000
39
    This is the solution of the equation.

    Convert the result to decimal form :
      A = 4648974.358974
