    Work: Find the solution of equation 28836*(500-x) = 1.038*(7930-3*0.487*x/0.3)*150 .
    Question type: Equation
    Solution:Original question:
     28836(500 − x ) =
519
500
(7930 − 3 ×
487
1000
 x ÷

) × 150
    Remove the bracket on the left of the equation:
     Left side of the equation = 28836 × 500 − 28836 x
                                             = 14418000 − 28836 x
    The equation is transformed into :
     14418000 − 28836 x =
519
500
(7930 − 3 ×
487
1000
 x ÷

) × 150
     Right side of the equation =
1557

(7930 − 3 ×
487
1000
 x ÷

)
    The equation is transformed into :
     14418000 − 28836 x =
1557
10
(7930 − 3 ×
487
1000
 x ÷

)
    Remove the bracket on the right of the equation:
     Right side of the equation =
1557
10
 × 7930 −
1557

                                               = 1234701 −
758259
1000
 x
    The equation is transformed into :
     14418000 − 28836 x = 1234701 −
758259
1000
 x

    Transposition :
      - 28836 x +
758259
1000
 x = 1234701 − 14418000

    Combine the items on the left of the equation:
      -
28077741
1000
 x = 1234701 − 14418000

    Combine the items on the right of the equation:
      -
28077741
1000
 x = - 13183299

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     13183299 =
28077741
1000
 x

    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 :
     
28077741
1000
 x = 13183299

    The coefficient of the unknown number is reduced to 1 :
      x = 13183299 ÷
28077741
1000
        = 13183299 ×
1000
28077741
        = 1464811 ×
1000
3119749

    We obtained :
      x =
1464811000
3119749
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 469.528478
