<PRE><B>Question 474992</B>
-5	x	+		y	=	-17	.............1				
1	y	=	3	+		x	---------2				
	y	=	3	+		x					
Substitute y in 		(1)									
-5x+(3+x)=-17
-5x+3+x	=-17			
-5x+x=-17-3				
-4x=-20								
/-4										
x=	5										
Plug the value of x in (1)											
-5	x	+		y	=	-17					
-5	*	5	+		y	=	-17				
-25	+		y	=	-17						
	y	=	8								
/	1										
y=	8
