Question 469734
2	x	+	1	y	=	6	.............1		
5	x		-2	y	=	6	.............2		
									
multiply (1)by 		2							
Multiply (2) by		1							
4	x	+	2	y	=	12			
5	x	+	-2	y	=	6			
Add the two equations									
9	x				=	18			
/	9								
x=2    				
plug value of 			x	in (1)					
2	x	+	1	y	=	6			
4		+	1	y	=	6			
			1	y	=	6		-4	
			1	y	=	2			
				y	=	2    
(2,2) is the solution
