[ 1/1 Equation]
    Work: Find the solution of equation 7926.1 = （440*21-x）*0.9+40*21 .
    Question type: Equation
    Solution:Original question:
     
79261
10
 = (440 × 21 − x ) ×
9
10
 + 40 × 21
     Right side of the equation = (440 × 21 − x ) ×
9
10
 + 840
    The equation is transformed into :
     
79261
10
 = (440 × 21 − x ) ×
9
10
 + 840
    Remove the bracket on the right of the equation:
     Right side of the equation = 440 × 21 ×
9
10
 − x ×
9
10
 + 840
                                               = 8316 − x ×
9
10
 + 840
                                               = 9156 −
9
10
 x
    The equation is transformed into :
     
79261
10
 = 9156 −
9
10
 x

    Transposition :
     
9
10
 x = 9156 −
79261
10

    Combine the items on the right of the equation:
     
9
10
 x =
12299
10

    The coefficient of the unknown number is reduced to 1 :
      x =
12299
10
 ÷
9
10
        =
12299
10
 ×
10
9
        = 12299 ×
1
9

    We obtained :
      x =
12299
9
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1366.555556
