[ 1/1 Equation]
    Work: Find the solution of equation ((X*2+6)*2+6)*2+6 = 999 .
    Question type: Equation
    Solution:Original question:
     (( X × 2 + 6) × 2 + 6) × 2 + 6 = 999
    Remove the bracket on the left of the equation:
     Left side of the equation = ( X × 2 + 6) × 2 × 2 + 6 × 2 + 6
                                             = ( X × 2 + 6) × 4 + 12 + 6
                                             = ( X × 2 + 6) × 4 + 18
                                             = X × 2 × 4 + 6 × 4 + 18
                                             = X × 8 + 24 + 18
                                             = 8 X + 42
    The equation is transformed into :
     8 X + 42 = 999

    Transposition :
     8 X = 99942

    Combine the items on the right of the equation:
     8 X = 957

    The coefficient of the unknown number is reduced to 1 :
      X = 957 ÷ 8
        = 957 ×
1
8

    We obtained :
      X =
957
8
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 119.625
