Question 999517


-1    	x	+	3    	y	=	6    	.............1					
3    	y	=	6    	+	1    	x						
/	3    	=										
	y	=	2    	+	 1/3	x						
4    	x	+	12    	y	=	0    		.....................2				
Substitute y in		(2)										
4    	x	+	12    	(	2    	+	 1/3	x	)	=	0    	
4    	x	+	24    	+	4    	x	=	0    				
4    	x		4    	x	=	-24    						
8    	x	=	-24    									
/	8    											
x=	-3    											
Plug the value of x in (1)												
-1    	x	+	3    	y	=	6    						
-1    	*	-3    	+	3    	y	=	6    					
3    	+	3    	y	=	6    							
3    	y	=	3    									
/	3    											
y=	1
