[ 1/1 Equation]
    Work: Find the solution of equation X2-9 = 0 .
    Question type: Equation
    Solution:Original question:
      X × 29 = 0

    Transposition :
     2 X = 0 + 9

    Combine the items on the right of the equation:
     2 X = 9

    The coefficient of the unknown number is reduced to 1 :
      X = 9 ÷ 2
        = 9 ×
1
2

    We obtained :
      X =
9
2
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 4.5
