Question 873173
3	x		-	y	=	2	.............1				
-1	y	=	2		-3	x					
/	-1	=									
	y	=	-2	+	3	x					
4	x	+	-3	y	=	-1		.....................2			
Substitute y in		(2)									
4	x	+	-3	(	-2	+	3	x	)	=	-1
4	x	+	6	+	-9	x	=	-1			
4	x		-9	x	=	-7					
-5	x	=	-7								
/	-5										
x=	7/ 5										
Plug the value of x in (1)											
3	x		-	y	=	2					
3	*	7/ 5		-	y	=	2				
21/ 5		-	y	=	2						
-1	y	=	-11/ 5								
/	-1										
y=	11/ 5
