Question 559391
Quarters---------x	numbers				
Dimes-----------y	numbers				
								
x+y=	500	.............1	
25x+10y	=6500	.............2	(convert $65 into cents)
Eliminate y								
multiply (1)by 		-10						
Multiply (2) by		1						
-10x-10y=-5000		
25x+10y	=6500		
Add the two equations								
15	x				=	1500		
/	15							
x	=	100		
plug value of 			x	in (1)				
1	x	+	1	y	=	500		
100		+	1	y	=	500		
			1	y	=	500		-100
			1	y	=	400		
				y	=	400 Quarters			100    	numbers				
Dimes			400    	numbers
