Question 703512
We solve by substitution method

-4	x	+	1	y	=	-11	.............1				
1	y	=	-11	+	4	x					
/	1	=									
	y	=	-11	+	4	x					
-5	x	+	-2	y	=	10		.....................2			
Substitute y in		(2)									
-5	x	+	-2	(	-11	+	4	x	)	=	10
-5	x	+	22	+	-8	x	=	10			
-5	x		-8	x	=	-12					
-13	x	=	-12								
/	-13										
x=	 12/13										
Plug the value of x in (1)											
-4	x	+	1	y	=	-11					
-4	*	 12/13	+	1	y	=	-11				
-48/13	+	1	y	=	-11						
1	y	=	-95/13								
y=	-95/13
