Question type: Equation
Solution:Original question:
| ( | 497 500 | − | x | ) | × | 300 | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 | + | 1 10 | + | 1 10 | + | 1 5 | + | 1 5 | = | ( | 497 500 | − | 769 1000 | ) | × | 300 | + | 1 10 |
| Left side of the equation = | ( | 497 500 | − | x | ) | × | 300 | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 | + | 3 5 |
| ( | 497 500 | − | x | ) | × | 300 | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 | + | 3 5 | = | ( | 497 500 | − | 769 1000 | ) | × | 300 | + | 1 10 |
| Left side of the equation = | 497 500 | × | 300 | − | x | × | 300 | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 | + | 3 5 |
| = | 1491 5 | − | x | × | 300 | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 | + | 3 5 |
| = | 1494 5 | − | 300 | x | + | ( | 409 500 | − | 79 100 | ) | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 |
| = | 1494 5 | − | 300 | x | + | 409 500 | × | 300 | − | 79 100 | × | 300 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 |
| = | 1494 5 | − | 300 | x | + | 1227 5 | − | 237 | + | ( | 819 1000 | − | 79 100 | ) | × | 300 |
| = | 1536 5 | − | 300 | x | + | ( | 819 1000 | − | 79 100 | ) | × | 300 |
| = | 1536 5 | − | 300 | x | + | 819 1000 | × | 300 | − | 79 100 | × | 300 |
| = | 1536 5 | − | 300 | x | + | 2457 10 | − | 237 |
| = | 3159 10 | − | 300 | x |
3159 10 | − | 300 | x | = | ( | 497 500 | − | 769 1000 | ) | × | 300 | + | 1 10 |
| Right side of the equation = | 497 500 | × | 300 | − | 769 1000 | × | 300 | + | 1 10 |
| = | 1491 5 | − | 2307 10 | + | 1 10 |
| = | 338 5 |
3159 10 | − | 300 | x | = | 338 5 |
Transposition :
| - | 300 | x | = | 338 5 | − | 3159 10 |
Combine the items on the right of the equation:
| - | 300 | x | = | - | 2483 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2483 10 | = | 300 | 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 :
| 300 | x | = | 2483 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2483 10 | ÷ | 300 |
| = | 2483 10 | × | 1 300 |
We obtained :
| x | = | 2483 3000 |
Convert the result to decimal form :
| x | = | 0.827667 |
