    Work: Find the solution of equation x-300 = 0.3x .
    Question type: Equation
    Solution:Original question:
      x 300 =
3
10
x

    Transposition :
      x
3
10
x = 300

    Combine the items on the left of the equation:
     
7
10
x = 300

    The coefficient of the unknown number is reduced to 1 :
      x = 300 ÷
7
10
        = 300 ×
10
7

    We obtained :
      x =
3000
7
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 428.571429
