[ 1/1 Equation]
    Work: Find the solution of equation 786-X/X*100% = 67.2% .
    Question type: Equation
    Solution:Original question:
     786 X ÷ X ×
100
100
=
336
500
     Multiply both sides of the equation by: X
     786 X X ×
100
100
=
336
500
X

    Transposition :
     786 X X ×
100
100
336
500
X = 0

    Combine the items on the left of the equation:
     
98041
125
X = 0

    The coefficient of the unknown number is reduced to 1 :
      X = 0 ÷
98041
125
        = 0 ×
125
98041

    We obtained :
      X = 0
    However,when simplifying the equation, multiply both sides by X , and when
      X = 0
    , its value is 0. Therefore, the value of this unknown number is not the solution of the equation, and the input to the equation is incorrect.
