设集合A={(X,y)/2x+y=6},B={(x,y)/3x+2y=4}满足C含于(A∩B)的集合C的个数为_____
设集合A={(X,y)/2x+y=6},B={(x,y)/3x+2y=4}满足C含于(A∩B)的集合C的个数为_____

设集合A={(X,y)/2x+y=6},B={(x,y)/3x+2y=4}满足C含于(A∩B)的集合C的个数为_____
集合A={(X,y)/2x+y=6},B={(x,y)/3x+2y=4}满足C含于(A∩B)的集合C的个数为_2____
AnB={(x,y)|(8,-10)}
所以,集合C={(8,-10)}和空集.共有二个.

2x+y =6 (1)
3x+2y=4 (2)
2(1)-(2)
x=8
y=-10
A∩B ={(8,-10)}
(A∩B)的集合C的个数为 1
