[ 1/1 Equation]
    Work: Find the solution of equation 15706 = [（220+220）*42-x]*0.9+8*42 .
    Question type: Equation
    Solution:Original question:
     15706 = ((220 + 220) × 42 − x ) ×
9
10
 + 8 × 42
     Right side of the equation = ((220 + 220) × 42 − x ) ×
9
10
 + 336
    The equation is transformed into :
     15706 = ((220 + 220) × 42 − x ) ×
9
10
 + 336
    Remove the bracket on the right of the equation:
     Right side of the equation = (220 + 220) × 42 ×
9
10
 − x ×

10
 + 336
                                               = (220 + 220) ×

    The equation is transformed into :
     15706 = 16968 −
9
10
 x

    Transposition :
     
9
10
 x = 16968 − 15706

    Combine the items on the right of the equation:
     
9
10
 x = 1262

    The coefficient of the unknown number is reduced to 1 :
      x = 1262 ÷
9
10
        = 1262 ×
10
9

    We obtained :
      x =
12620
9
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1402.222222
