[ 1/1 Equation]
    Work: Find the solution of equation （((x×3×1.75)/1500)+((x×1.6)-1500)）×20 = 300000 .
    Question type: Equation
    Solution:Original question:
     ((( x × 3 ×

) − 1500)) × 20 = 300000
    Remove the bracket on the left of the equation:
     Left side of the equation = (( x × 3 ×

100
 x − 30000
    The equation is transformed into :
     
3207
100
 x − 30000 = 300000

    Transposition :
     
3207
100
 x = 300000 + 30000

    Combine the items on the right of the equation:
     
3207
100
 x = 330000

    The coefficient of the unknown number is reduced to 1 :
      x = 330000 ÷
3207
100
        = 330000 ×
100
3207
        = 110000 ×
100
1069

    We obtained :
      x =
11000000
1069
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 10289.990645
