You are almost there.

-2	x	+	1	y	=	3	.............1	
1	x	+	1	y	=	-4	.............2	
Eliminate y								
multiply (1)by 		-1						
Multiply (2) by		1						
2	x		-1	y	=	-3		
1	x		1	y	=	-4		
Add the two equations								
3	x				=	-7		
/	3							
x	=	-2.33		OR	-2  1/ 3			
plug value of 			x	in (1)				
-2	x	+	1	y	=	3		
4.67		+	1	y	=	3		
			1	y	=	3		-4.67
			1	y	=	-1.67		
				y	=	-1.67		

equation1					
when x=	0	y=	3	(	0	,	3	)	3    
when y =	0	x=	-1.5	(	-1.5	,	0	)	
Equation 2									
when x=	0	y=	-4	(	0	,	-4	)	-4    
when y =	0	x=	-4	(	-4	,	0	)
