Question 694134
4	x	+	1	y	=	-8	.............1	
								
3x+3y=3 
/3

1	x	+	1	y	=	1	.............2	
Eliminate	y							
							
multiply (1)by		-1						
Multiply (2) by		1						
-4	x		-1	y	=	8		
1	x	+	1	y	=	1		
Add the two equations								
-3	x				=	9		
/	-3							
x	=	-3						
plug value of			x	in (1)				
4	x	+	1	y	=	-8		
-12		+		y	=	-8		
				y	=	-8	+	12
				y	=	4		
				y	=	4		
x=	-3						
y=	4
