    Work: Find the solution of equation 【20833x+4583(12-x)+1700*12】*10.5+(21000+5000x) = 2000000 .
    Question type: Equation
    Solution:Original question:
     (20833 x + 4583(12 − x ) + 1700 × 12) ×

 + (21000 + 5000 x ) = 2000000
    Remove the bracket on the left of the equation:
     Left side of the equation = 20833 x ×

 x + 214200 + (21000 + 5000 x )
                                             = 170625 x + 791658 + (21000 + 5000 x )
                                             = 170625 x + 791658 + 21000 + 5000 x
                                             = 175625 x + 812658
    The equation is transformed into :
     175625 x + 812658 = 2000000

    Transposition :
     175625 x = 2000000 − 812658

    Combine the items on the right of the equation:
     175625 x = 1187342

    The coefficient of the unknown number is reduced to 1 :
      x = 1187342 ÷ 175625
        = 1187342 ×
1
175625

    We obtained :
      x =
1187342
175625
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 6.760666
