Question 681437
1	x	+	2	y	=	3................(1)
						
3	x	+	2	y	=	5................(2)
Eliminate	y					
multiply (1)by		-1				
Multiply (2) by		1				
-1	x		-2	y	=	-3
3	x	+	2	y	=	5
Add the two equations						
2	x				=	2
/	2					
x	=	1				
plug value of			x	in (1)		
1	x	+	2	y	=	3
1		+	2	y	=	3
			2	y	=	3
			2	y	=	2
				y	=	1
x=	1				
y=	1	

The solution (1,1)
