A	A	A	P	11
P	Y	P	U	X
U	Y	U	U	11
P	P	P	A	9
8	21	8	7

A = ?, P = ? Y = ? U = ? X = ?

[显示答案][隐藏答案]

A = 3, P = 2, Y = 8, U = 1, X = 13

3A	+	P	=	11	------ (1)
A	+	3P	=	9	------ (2)
(2) x 3 :
3A	+	9P	=	27	------ (3)
(3) - (1):
		8P	=	16
		P	=	2
From (2):
		A	=	9	-	3P
		A	=	9	-	3(2)
		A	=	3
From table:
		U	=	8	-	A	-	2P
		U	=	8	-	3	-	2(2)
		U	=	1
		2Y	=	21	-	A	-	P
		2Y	=	21	-	3	-	2
		2Y	=	16
		Y	=	8
		X	=	2P	+	Y	+	U
		X	=	2(2)	+	8	+	1
		X	=	13
