Question 484171
-4	x	+	1	y	=	1	.............1				
2	y	=	12	+	3	x	---------2				
/	2	=									
	y	=	6	+	1.5	x					
Substitute y in 		(1)									
-4	x	+	1	(	6	+	1.5	x	)	=	1
-4	x	+	6	+	1.5	x	=	1			
-4	x	+	1.5	x	=	1	-6				
-2.5	x	=	-5								
/	-2.5										
x=	2										
Plug the value of x in (1)											
-4	x	+	1	y	=	1					
-4	*	2	+	1	y	=	1				
-8	+	1	y	=	1						
1	y	=	9								
/	1										
y=	9
