1	x	+	4	y	=	1	.............1	
								
3	x	+	2	y	=	-12	.............2	
Eliminate	y							
multiply (1)by		1						
Multiply (2) by		-2						
1	x		4	y	=	1		
-6	x		-4	y	=	24		
Add the two equations								
-5	x				=	25		
/	-5							
x	=	-5						
plug value of			x	in (1)				
1	x	+	4	y	=	1		
-5		+	4	y	=	1		
			4	y	=	1	+	5
			4	y	=	6		
				y	=	2		
x=	-5						
y=	2	
---------------

3	x	+	2	y	=	6	.............1	
								
1	x		-4	y	=	-6	.............2	
Eliminate	y							
multiply (1)by		2						
Multiply (2) by		1						
6	x		4	y	=	12		
1	x		-4	y	=	-6		
Add the two equations								
7	x				=	6		
/	7							
x	=	1						
plug value of			x	in (1)				
3	x	+	2	y	=	6		
3		+	2	y	=	6		
			2	y	=	6		-3
			2	y	=	3		
				y	=	2		
x=	1						
y=	2
