Question 874649
x= 	number of 	dimes						
y=	number of 	nickels						
 								
1	x	+	1	y	=	180	.............1	
								
10	x	+	5	y	=	1065	.............2	
Eliminate	y							
multiply (1)by		-5						
Multiply (2) by		1						
-5	x		-5	y	=	-900		
10	x	+	5	y	=	1065		
Add the two equations								
5	x				=	165		
/	5							
x	=	33      						
plug value of			x	in (1)				
1	x	+	1	y	=	180		
33		+		y	=	180		
				y	=	180		-33
				y	=	147		
				y	=	147		
x=	33		number of 	dimes				
y=	147		number of 	nickels
