Question type: Equation
Solution:Original question:
| A | = | 29498400 | + | 665856 | + | 10000000 | × | 1 200 | + | 20000000 | × | 1 500 | + | ( | A | − | 30000000 | ) | × | 3 2000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| Right side of the equation = | 29498400 | + | 665856 | + | 50000 | + | 40000 | + | ( | A | − | 30000000 | ) | × | 3 2000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 30254256 | + | ( | A | − | 30000000 | ) | × | 3 2000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| A | = | 30254256 | + | ( | A | − | 30000000 | ) | × | 3 2000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| Right side of the equation = | 30254256 | + | A | × | 3 2000 | − | 30000000 | × | 3 2000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 30254256 | + | A | × | 3 2000 | − | 45000 | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 30209256 | + | 3 2000 | A | + | ( | A | − | 29498400 | ) | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 30209256 | + | 3 2000 | A | + | A | × | 3 50 | − | 29498400 | × | 3 50 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 30209256 | + | 3 2000 | A | + | A | × | 3 50 | − | 1769904 | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 28439352 | + | 123 2000 | A | + | 9 1250 | ( | A | − | 29498400 | ) |
| = | 28439352 | + | 123 2000 | A | + | 9 1250 | A | − | 9 1250 | × | 29498400 |
| = | 28439352 | + | 123 2000 | A | + | 9 1250 | A | − | 5309712 25 |
| = | 705674088 25 | + | 687 10000 | A |
| A | = | 705674088 25 | + | 687 10000 | A |
Transposition :
| A | − | 687 10000 | A | = | 705674088 25 |
Combine the items on the left of the equation:
9313 10000 | A | = | 705674088 25 |
The coefficient of the unknown number is reduced to 1 :
| A | = | 705674088 25 | ÷ | 9313 10000 |
| = | 705674088 25 | × | 10000 9313 |
| = | 705674088 | × | 400 9313 |
We obtained :
| A | = | 282269635200 9313 |
