[ 1/1 Equation]
    Work: Find the solution of equation 21679.45 = [(220+220)*63-x]*0.85+8*63 .
    Question type: Equation
    Solution:Original question:
     
433589
20
 = ((220 + 220) × 63 − x ) ×
17
20
 + 8 × 63
     Right side of the equation = ((220 + 220) × 63 − x ) ×
17
20
 + 504
    The equation is transformed into :
     
433589
20
 = ((220 + 220) × 63 − x ) ×
17
20
 + 504
    Remove the bracket on the right of the equation:
     Right side of the equation = (220 + 220) × 63 ×
17
20
 − x ×
17
20
 + 504
                                               = (220 + 220) ×

20
 − x ×
17
20
 + 504
                                               = 220 ×

20
 x + 504
                                               = 11781 + 11781 −
17
20
 x + 504
                                               = 24066 −
17
20
 x
    The equation is transformed into :
     
433589
20
 = 24066 −
17
20
 x

    Transposition :
     
17
20
 x = 24066 −
433589
20

    Combine the items on the right of the equation:
     
17
20
 x =
47731
20

    The coefficient of the unknown number is reduced to 1 :
      x =
47731
20
 ÷
17
20
        =
47731
20
 ×
20
17
        = 47731 ×
1
17

    We obtained :
      x =
47731
17
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2807.705882
