MULTIPLE CHOICE QUESTION
2 mins • 1 pt
(2 , 2) 是否方程3x - 2y = 1 的解？
Yes
No
Answer explanation
將 x = 2，y = 2 代入方程
3x - 2y = 1
左邊 = 3（2） - 2（2） = 2
右邊 = 1
左邊 不等於 右邊
所以 （2，2）不是方程的解。
2.
MULTIPLE CHOICE QUESTION
2 mins • 1 pt
(-2 , 2) 是否方程x + 2y = 1 的解？
Yes
No
Answer explanation
將 x = -2，y = 2 代入方程
x + 2y = 1
左邊 = （-2） + 2（2） = 2
右邊 = 1
左邊 不等於 右邊
所以 （-2，2）不是方程的解。

(-1 , 1) 是否方程x + 2y = 1 的解？
Yes
No
Answer explanation
將 x = -1，y = 1 代入方程
x + 2y = 1
左邊 = （-1） + 2（1） = 1
右邊 = 1
左邊 等於 右邊
所以 （-1，1）是方程的解。
