2	x	+	4	y	=	-6	.............1				
4	y	=	-6	+	-2	x					
/	4	=									
	y	=	-1.5	+	-0.5	x					
1	x	+	-3	y	=	7		.....................2			
Substitute y in		(2)									
1	x	+	-3	(	-1.5	+	-0.5	x	)	=	7
1	x	+	4.5	+	1.5	x	=	7			
1	x		1.5	x	=	2.5					
2.5	x	=	2.5								
/	2.5										
x=	1      										
Plug the value of x in (1)											
2	x	+	4	y	=	-6					
2	*	1      	+	4	y	=	-6				
2      	+	4	y	=	-6						
4	y	=	-8      								
/	4										
y=	-2     

x=1,y=-2
