[ 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 ×
7
4
) − 1500) + (( x ×
8
5
) − 1500)) × 20 = 300000
    Remove the bracket on the left of the equation:
     Left side of the equation = (( x × 3 ×

5
) − 1500) × 20
                                             = ( x × 3 ×

) − 1500) × 20
                                             = ( x × 3 ×

                                             = x × 3 ×
7

 × 20 − 30000 + (( x ×

) − 1500) × 20
                                             = x × 105 − 30000 + (( x ×
8
5
) − 1500) × 20
                                             = 105 x − 30000 + ( x ×
8
5
) × 20 − 1500 × 20
                                             = 105 x − 30000 + ( x ×
8
5
) × 20 − 30000
                                             = 105 x − 60000 + ( x ×
8
5
) × 20
                                             = 105 x − 60000 + x ×
8
5
 × 20
                                             = 105 x − 60000 + x × 32
                                             = 137 x − 60000
    The equation is transformed into :
     137 x − 60000 = 300000

    Transposition :
     137 x = 300000 + 60000

    Combine the items on the right of the equation:
     137 x = 360000

    The coefficient of the unknown number is reduced to 1 :
      x = 360000 ÷ 137
        = 360000 ×
1
137

    We obtained :
      x =
360000
137
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2627.737226
