[ 1/1 Equation]
    Work: Find the solution of equation 1200*（1-120/P）*12.5 = 12000 .
    Question type: Equation
    Solution:Original question:
     1200(1 − 120 ÷ P ) ×
25
2
 = 12000
    Remove a bracket on the left of the equation:：
     1200 × 1 ×
25
2
 − 1200 × 120 ÷ P ×
25
2
 = 12000
    The equation is reduced to :
     15000 − 1800000 ÷ P = 12000
     Multiply both sides of the equation by: P
     15000 P − 1800000 = 12000 P

    Transposition :
     15000 P − 12000 P = 1800000

    Combine the items on the left of the equation:
     3000 P = 1800000

    The coefficient of the unknown number is reduced to 1 :
      P = 1800000 ÷ 3000
        = 1800000 ×
1
3000
        = 600 × 1

    We obtained :
      P = 600
    This is the solution of the equation.
