[ 1/1 Equation]
    Work: Find the solution of equation 3(1-2y)-2y = 5 .
    Question type: Equation
    Solution:Original question:
     3(12 y )2 y = 5
    Remove the bracket on the left of the equation:
     Left side of the equation = 3 × 13 × 2 y 2 y
                                             = 36 y 2 y
                                             = 38 y
    The equation is transformed into :
     38 y = 5

    Transposition :
      - 8 y = 53

    Combine the items on the right of the equation:
      - 8 y = 2

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 2 = 8 y

    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 :
     8 y = - 2

    The coefficient of the unknown number is reduced to 1 :
      y = - 2 ÷ 8
        = - 2 ×
1
8
        = - 1 ×
1
4

    We obtained :
      y = -
1
4
    This is the solution of the equation.

    Convert the result to decimal form :
      y = - 0.25
