Question 730132
2	x	+	-	y	=	2	.............1				
-	y	=	2	+	-2	x					
/	-1	=									
	y	=	-2	+	2	x					
7	x	+	-3	y	=	10		.....................2			
Substitute y in		(2)									
7	x		-3	(	-2	+	2	x	)	=	10
7	x	+	6	+	-6	x	=	10			
7	x		-6	x	=	4					
1	x	=	4								
/	1										
x=	4      										
Plug the value of x in (1)											
2	x		-	y	=	2					
2	*	4      		-	y	=	2				
8      	+	-	y	=	2						
-1	y	=	-6      								
/	-1										
y=	6
