Question 714664

Make y the subject in the first equation and substitute in equation (2)
-2	x	+	1	y	=	-2	.............1		y	=	-2	+	2	x					
3	x	+	4	y	=	3 	.....................2			
Substitute y in		(2)									
3x+	4	(	-2	+	2	x	)	=	3
3	x	+	-8	+	8	x	=	3			
3	x		8	x	=	11					
11	x	=	11								
/	11										
x=	1      										
Plug the value of x in (1)											
-2	x	+	1	y	=	-2					
-2	*	1      	+	1	y	=	-2				
-2      	+	1	y	=	-2						
y	=	0
