二元一次方程组100道

以下是一个包含100个二元一次方程组的示例。每个方程组包含两个方程，形式为 ax + by = c 和 dx + ey = f。

1. 2x + 3y = 8

3x 2y = 1

2. 5x + 4y = 18

2x y = 3

3. x + 2y = 7

3x y = 5

4. 4x 3y = 2

2x + y = 6

5. 3x + 2y = 12

2x y = 4

6. x 3y = 2

2x + y = 8

7. 4x + 5y = 14

3x 2y = 6

8. 2x + y = 5

3x 2y = 1

9. x + 4y = 9

3x 2y = 1

10. 5x 3y = 10

2x + y = 4

...
