[ 1/1 Equation]
    Work: Find the solution of equation 60*(2x+x+2) = 55*(2x+2)+60*x .
    Question type: Equation
    Solution:Original question:
     60(2 x + x + 2) = 55(2 x + 2) + 60 x
    Remove the bracket on the left of the equation:
     Left side of the equation = 60 × 2 x + 60 x + 60 × 2
                                             = 120 x + 60 x + 120
                                             = 180 x + 120
    The equation is transformed into :
     180 x + 120 = 55(2 x + 2) + 60 x
    Remove the bracket on the right of the equation:
     Right side of the equation = 55 × 2 x + 55 × 2 + 60 x
                                               = 110 x + 110 + 60 x
                                               = 170 x + 110
    The equation is transformed into :
     180 x + 120 = 170 x + 110

    Transposition :
     180 x 170 x = 110120

    Combine the items on the left of the equation:
     10 x = 110120

    Combine the items on the right of the equation:
     10 x = - 10

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

    We obtained :
      x = - 1
    This is the solution of the equation.
