Question 683544
2	x	+	3	y	=	200	.............1	
								
5	x	+	4	y	=	290	.............2	
Eliminate	y							
multiply (1)by		-4						
Multiply (2) by		3						
-8	x		-12	y	=	-800		
15	x	+	12	y	=	870		
Add the two equations								
7	x				=	70		
/	7							
x	=	10						
plug value of			x	in (1)				
2	x	+	3	y	=	200		
20		+	3	y	=	200		
			3	y	=	200		-20
			3	y	=	180		
				y	=	60		
x=	10						
y=	60
