[ 1/1 Equation]
    Work: Find the solution of equation (1+2X)/3 = X-1 .
    Question type: Equation
    Solution:Original question:
     (1 + 2 X ) ÷ 3 = X 1
    Remove the bracket on the left of the equation:
     Left side of the equation = 1 ×
1
3
+ 2 X ×
1
3
                                             =
1
3
+
2
3
X
    The equation is transformed into :
     
1
3
+
2
3
X = X 1

    Transposition :
     
2
3
X X = - 1
1
3

    Combine the items on the left of the equation:
     
1
3
X = - 1
1
3

    Combine the items on the right of the equation:
     
1
3
X = -
4
3

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
4
3
=
1
3
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
3
X =
4
3

    The coefficient of the unknown number is reduced to 1 :
      X =
4
3
÷
1
3
        =
4
3
× 3
        = 4 × 1

    We obtained :
      X = 4
    This is the solution of the equation.
