Work: Find the solution of equation C210.4×(1-0.4)×0.2 = 0 .
Question type: Equation
Solution:Original question:
| C | × | 1052 5 | ( | 1 | − | 2 5 | ) | × | 1 5 | = | 0 |
| Left side of the equation = | C | × | 1052 25 | ( | 1 | − | 2 5 | ) |
| C | × | 1052 25 | ( | 1 | − | 2 5 | ) | = | 0 |
| Left side of the equation = | C | × | 1052 25 | × | 1 | − | C | × | 1052 25 | × | 2 5 |
| = | C | × | 1052 25 | − | C | × | 2104 125 |
| = | 3156 125 | C |
3156 125 | C | = | 0 |
The coefficient of the unknown number is reduced to 1 :
| C | = | 0 | ÷ | 3156 125 |
| = | 0 | × | 125 3156 |
We obtained :
| C | = | 0 |
