[ 1/1 Equation]
    Work: Find the solution of equation 120-0.25P = 20+0.5P .
    Question type: Equation
    Solution:Original question:
     120
1
4
P = 20 +
1
2
P

    Transposition :
      -
1
4
P
1
2
P = 20120

    Combine the items on the left of the equation:
      -
3
4
P = 20120

    Combine the items on the right of the equation:
      -
3
4
P = - 100

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     100 =
3
4
P

    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
4
P = 100

    The coefficient of the unknown number is reduced to 1 :
      P = 100 ÷
3
4
        = 100 ×
4
3

    We obtained :
      P =
400
3
    This is the solution of the equation.

    Convert the result to decimal form :
      P = 133.333333
