Nickels			x	numbers					
Quarters			y	numbers					
									
1	x	+	1	y	=	33	.............1		
5	x	+	25	y	=	605	.............2		
Eliminate y									
multiply (1)by 		-25							
Multiply (2) by		1							
-25	x		-25	y	=	-825			
5	x		25	y	=	605			
Add the two equations									
-20	x				=	-220			
/	-20								
x	=	11				
plug value of 			x	in (1)					
1	x	+	1	y	=	33			
11		+	1	y	=	33			
			1	y	=	33		-11	
			1	y	=	22			
				y	=	22
