[ 1/1 Equation]
    Work: Find the solution of equation 120+450x = 100+500x .
    Question type: Equation
    Solution:Original question:
     120 + 450 x = 100 + 500 x

    Transposition :
     450 x 500 x = 100120

    Combine the items on the left of the equation:
      - 50 x = 100120

    Combine the items on the right of the equation:
      - 50 x = - 20

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     20 = 50 x

    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 :
     50 x = 20

    The coefficient of the unknown number is reduced to 1 :
      x = 20 ÷ 50
        = 20 ×
1
50
        = 2 ×
1
5

    We obtained :
      x =
2
5
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.4
