[ 1/1 Equation]
    Work: Find the solution of equation 2+1/6(x-2-1/5x) = 1/5(x-2) .
    Question type: Equation
    Solution:Original question:
     2 + 1 ÷ 6 × ( x 21 ÷ 5 × x ) = 1 ÷ 5 × ( x 2)
     Left side of the equation = 2 +
1
6
( x 21 ÷ 5 × x )
    The equation is transformed into :
     2 +
1
6
( x 21 ÷ 5 × x ) = 1 ÷ 5 × ( x 2)
    Remove the bracket on the left of the equation:
     Left side of the equation = 2 +

x = 1 ÷ 5 × ( x 2)
     Right side of the equation =
1
5
( x 2)
    The equation is transformed into :
     
5

( x 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
15
x = -
2

    Combine the items on the right of the equation:
      -
1
15
x = -
31
15

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
31
15
=
1
15
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
15
x =
31
15

    The coefficient of the unknown number is reduced to 1 :
      x =
31
15
÷
1
15
        =
31
15
× 15
        = 31 × 1

    We obtained :
      x = 31
    This is the solution of the equation.
