[ 1/1 Equation]
    Work: Find the solution of equation 225-(1/2)a = a .
    Question type: Equation
    Solution:Original question:
     225(1 ÷ 2) a = a
    Remove the bracket on the left of the equation:
     Left side of the equation = 2251 ÷ 2 × a
                                             = 225
1
2
a
    The equation is transformed into :
     225
1
2
a = a

    Transposition :
      -
1
2
a a = - 225

    Combine the items on the left of the equation:
      -
3
2
a = - 225

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     225 =
3
2
a

    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 :
     
3
2
a = 225

    The coefficient of the unknown number is reduced to 1 :
      a = 225 ÷
3
2
        = 225 ×
2
3
        = 75 × 2

    We obtained :
      a = 150
    This is the solution of the equation.
