[ 1/1 Equation]
    Work: Find the solution of equation (100*10000+900000)*20% = 10000*p*(1-5%)-1900000 .
    Question type: Equation
    Solution:Original question:
     (100 × 10000 + 900000) ×
20
100
= 10000 p (1
5
100
)1900000
    Remove the bracket on the left of the equation:
     Left side of the equation = 100 × 10000 ×
20
100
+ 900000 ×
20
100
                                             = 200000 + 180000
                                             = 380000
    The equation is transformed into :
     380000 = 10000 p (1
5
100
)1900000
    Remove the bracket on the right of the equation:
     Right side of the equation = 10000 p × 110000 p ×
5
100
1900000
                                               = 10000 p 500 p 1900000
                                               = 9500 p 1900000
    The equation is transformed into :
     380000 = 9500 p 1900000

    Transposition :
      - 9500 p = - 1900000380000

    Combine the items on the right of the equation:
      - 9500 p = - 2280000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     2280000 = 9500 p

    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 :
     9500 p = 2280000

    The coefficient of the unknown number is reduced to 1 :
      p = 2280000 ÷ 9500
        = 2280000 ×
1
9500
        = 240 × 1

    We obtained :
      p = 240
    This is the solution of the equation.
