Work: Find the solution of equation X-（X-800）*0.2-X/1.01*0.01-X/1.01*0.01*0.07*0.5 = 3000 .
Question type: Equation
Solution:Original question:
| X | − | ( | X | − | 800 | ) | × | 1 5 | − | X | ÷ | 101 100 | × | 1 100 | − | X | ÷ | 101 100 | × | 1 100 | × | 7 100 | × | 1 2 | = | 3000 |
| Left side of the equation = | X | − | ( | X | − | 800 | ) | × | 1 5 | − | X | × | 1 101 | − | X | × | 7 20200 |
| = | 19993 20200 | X | − | ( | X | − | 800 | ) | × | 1 5 |
19993 20200 | X | − | ( | X | − | 800 | ) | × | 1 5 | = | 3000 |
| Left side of the equation = | 19993 20200 | X | − | X | × | 1 5 | + | 800 | × | 1 5 |
| = | 19993 20200 | X | − | X | × | 1 5 | + | 160 |
| = | 15953 20200 | X | + | 160 |
15953 20200 | X | + | 160 | = | 3000 |
Transposition :
15953 20200 | X | = | 3000 | − | 160 |
Combine the items on the right of the equation:
15953 20200 | X | = | 2840 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2840 | ÷ | 15953 20200 |
| = | 2840 | × | 20200 15953 |
We obtained :
| X | = | 57368000 15953 |
Convert the result to decimal form :
| X | = | 3596.063436 |
