[ 1/1 Equation]
    Work: Find the solution of equation x+5+1/2x+4 = 2x .
    Question type: Equation
    Solution:Original question:
      x + 5 + 1 ÷ 2 × x + 4 = 2 x
     Left side of the equation = x + 5 +
1
2
x + 4
                                             =
3
2
x + 9
    The equation is transformed into :
     
3
2
x + 9 = 2 x

    Transposition :
     
3
2
x 2 x = - 9

    Combine the items on the left of the equation:
      -
1
2
x = - 9

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     9 =
1
2
x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
1
2
x = 9

    The coefficient of the unknown number is reduced to 1 :
      x = 9 ÷
1
2
        = 9 × 2

    We obtained :
      x = 18
    This is the solution of the equation.
