Question 1028967
4	x		-7	y	=	0	.............1	
Total value								
500	x	+	400	y	=	10200	.............2	
Eliminate	y							
multiply (1)by		400						
Multiply (2) by		7						
1600	x		-2800	y	=	0		
3500	x	+	2800	y	=	71400		
Add the two equations								
5100	x				=	71400		
/	5100							
x	=	14						
plug value of			x	in (1)				
4	x		-7	y	=	0		
56			-7	y	=	0		
			-7	y	=	0		-56
			-7	y	=	-56		
				y	=	8		
x=	14		cost of	large candies in cents				
y=	8		cost of	small candies in cents
