Detailed information: The input equation set is:
 | | | | | | 371 50 | x | + | | | 434 5 | y | = | | | 1527 50 | | (1) |
| | | | 4127 50 | x | + | | | 427 50 | y | = | | | 1777 50 | | (2) |
| Question solving process:
Multiply both sides of equation (1) by 4127 Divide the two sides of equation (1) by 371, the equation can be obtained: | | | | 4127 50 | x | + | | | 255874 265 | y | = | | | 6301929 18550 | (3) | , then subtract both sides of equation (3) from both sides of equation (2), the equations are reduced to:
 | | | | | | 371 50 | x | + | | | 434 5 | y | = | | | 1527 50 | | (1) |
| | - | 2536109 2650 | y | = | | - | 2821331 9275 | | (2) |
|
Multiply both sides of equation (2) by 230020 Divide both sides of equation (2) by 2536109, get the equation:| | - | 4185062 48215 | y | = | | - | 5178396 2555395 | (4) | , then add the two sides of equation (4) to both sides of equation (1), get the equation:
 | | | | | | 371 50 | x | = | | | 728633673 25553950 | | (1) |
| | - | 2536109 2650 | y | = | | - | 2821331 9275 | | (2) |
|
The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 | | | | | x | = | | | 728633673 189610309 | | (1) |
| |
Therefore, the solution of the equation set is:
