-3	x	+	1	y	=	19	.............1			
1	y	=	19		3	x	---------2			
/	1	=								
	y	=	19		3	x				
Substitute y in		(2)								
9	x	+	2	(	19		3	x	)	=
9	x	+	38	+	6	x	=	-37		
9	x		6	x	=	-75				
15	x	=	-75							
/	15									
x=	-5									
Plug the value of x in (1)										
9	x	+	2	y	=	-37				
9	*	-5	+	2	y	=	-37			
-45	+	2	y	=	-37
