[ 1/1 Equation]
    Work: Find the solution of equation 500000*P*（1-5%）-500000*80-3000000 = 0 .
    Question type: Equation
    Solution:Original question:
     500000 P (1 −
5
100
) − 500000 × 80 − 3000000 = 0
     Left side of the equation = 500000 P (1 −
5
100
) − 40000000 − 3000000
                                             = 500000 P (1 −
5
100
) − 43000000
    The equation is transformed into :
     500000 P (1 −
5
100
) − 43000000 = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 500000 P × 1 − 500000 P ×
5
100
 − 43000000
                                             = 500000 P − 25000 P − 43000000
                                             = 475000 P − 43000000
    The equation is transformed into :
     475000 P − 43000000 = 0

    Transposition :
     475000 P = 0 + 43000000

    Combine the items on the right of the equation:
     475000 P = 43000000

    The coefficient of the unknown number is reduced to 1 :
      P = 43000000 ÷ 475000
        = 43000000 ×
1
475000
        = 1720 ×
1
19

    We obtained :
      P =
1720
19
    This is the solution of the equation.

    Convert the result to decimal form :
      P = 90.526316
