Question 534155
1	x		-4	y	=	4	.............1				
-3	y	=	-18		-6	x	---------2				
/	-3	=									
	y	=	6	+	2	x					
Substitute y in 		(1)									
1	x		-4	(	6	+	2	x	)	=	4
1	x		-24	+	-8	x	=	4			
1	x		-8	x	=	4	24				
-7	x	=	28								
/	-7										
x=	-4										
Plug the value of x in (1)											
1	x		-4	y	=	4					
1	*	-4		-4	y	=	4				
-4		-4	y	=	4						
-4	y	=	8								
/	-4										
y=	-2
