[ 2/6 Equation]
    Work: Find the solution of equation ８(x＋７３) = ７９２ .
    Question type: Equation
    Solution:Original question:
     8( x + 73) = 792
    Remove the bracket on the left of the equation:
     Left side of the equation = 8 x + 8 × 73
                                             = 8 x + 584
    The equation is transformed into :
     8 x + 584 = 792

    Transposition :
     8 x = 792 − 584

    Combine the items on the right of the equation:
     8 x = 208

    The coefficient of the unknown number is reduced to 1 :
      x = 208 ÷ 8
        = 208 ×

8
        = 26 × 1

    We obtained :
      x = 26
    This is the solution of the equation.

[ 3/6 Equation]
    Work: Find the solution of equation ４x×２＋１２ = ６４－５x .
    Question type: Equation
    Solution:Original question:
     4 x × 2 + 12 = 64 − 5 x
     Left side of the equation = 8 x + 12
    The equation is transformed into :
     8 x + 12 = 64 − 5 x

    Transposition :
     8 x + 5 x = 64 − 12

    Combine the items on the left of the equation:
     13 x = 64 − 12

    Combine the items on the right of the equation:
     13 x = 52

    The coefficient of the unknown number is reduced to 1 :
      x = 52 ÷ 13
        = 52 ×

    Question type: Equation
    Solution:Original question:
     4 x × 2 − x − 14 = 35
     Left side of the equation = 8 x − x − 14
                                             = 7 x − 14
    The equation is transformed into :
     7 x − 14 = 35

    Transposition :
     7 x = 35 + 14

    Combine the items on the right of the equation:
     7 x = 49

    The coefficient of the unknown number is reduced to 1 :
      x = 49 ÷ 7
        = 49 ×

     4 x + 44 = 60 − 4 x

    Transposition :
     4 x + 4 x = 60 − 44

    Combine the items on the left of the equation:
     8 x = 60 − 44

    Combine the items on the right of the equation:
     8 x = 16

    The coefficient of the unknown number is reduced to 1 :
      x = 16 ÷ 8
        = 16 ×
