Question 670489
x= 	Chocolate covered peanuts			pounds				
y=	Chocolate covered cashewnuts			pounds				
Total nuts sold								
1	x		-1	y	=	245	.............1	
Cost  of nuts								
7	x	+	14	y	=	9*245	.............2	
Eliminate	y							
multiply (1)by		14						
Multiply (2) by		1						
14	x		-14	y	=	3430		
7	x	+	14	y	=	2205		
Add the two equations								
21	x				=	5635		
/	21							
x	=	268						
plug value of			x	in (1)				
1	x		-1	y	=	245		
268			-1	y	=	245		
			-1	y	=	245		-268
			-1	y	=	-23		
				y	=	23
