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

X +
1
6
= 2 ÷ 3 × ( X 1 ÷ 2)
     Right side of the equation =
2

( X 1 ÷ 2)
    The equation is transformed into :
     
1

( X 1 ÷ 2)
    Remove the bracket on the right of the equation:
     Right side of the equation =

    Combine the items on the left of the equation:
      -
1

1
6

    Combine the items on the right of the equation:
      -
1
2
X = -
1
2

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

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

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