Question 461139
1	x	+	3	y	=	3	.............1				
-4	y	=	6		-2	x	---------2				
/	-4	=									
	y	=	-1.5	+	0.5	x					
Substitute y in 		(1)									
1	x	+	3	(	-1.5	+	0.5	x	)	=	3
1	x		-4.5	+	1.5	x	=	3			
1	x	+	1.5	x	=	3	4.5				
2.5	x	=	7.5								
/	2.5										
x=	3										
Plug the value of x in (1)											
1	x	+	3	y	=	3					
1	*	3	+	3	y	=	3				
3	+	3	y	=	3						
3	y	=	0								
/	3										
y=	0
