Work: Find the solution of equation 800000-X+(X/1.01*0.01)*1.12 = （800000/1.06*0.06）*1.12 .
Question type: Equation
Solution:Original question:
| 800000 | − | X | + | ( | X | ÷ | 101 100 | × | 1 100 | ) | × | 28 25 | = | ( | 800000 | ÷ | 53 50 | × | 3 50 | ) | × | 28 25 |
| Left side of the equation = | 800000 | − | X | + | X | ÷ | 101 100 | × | 1 100 | × | 28 25 |
| = | 800000 | − | X | + | X | × | 28 2525 |
| = | 800000 | − | 2497 2525 | X |
| 800000 | − | 2497 2525 | X | = | ( | 800000 | ÷ | 53 50 | × | 3 50 | ) | × | 28 25 |
| Right side of the equation = | 800000 | ÷ | 53 50 | × | 3 50 | × | 28 25 |
| = | 2688000 53 |
| 800000 | − | 2497 2525 | X | = | 2688000 53 |
Transposition :
| - | 2497 2525 | X | = | 2688000 53 | − | 800000 |
Combine the items on the right of the equation:
| - | 2497 2525 | X | = | - | 39712000 53 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
39712000 53 | = | 2497 2525 | 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 :
2497 2525 | X | = | 39712000 53 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 39712000 53 | ÷ | 2497 2525 |
| = | 39712000 53 | × | 2525 2497 |
We obtained :
| X | = | 100272800000 132341 |
