Question 458303
Nickels	x							
Dimes	y							
								
1	x	+	1	y	=	80	.............1	
5	x	+	10	y	=	610	.............2	
								
multiply (1)by 		-10						
Multiply (2) by		1						
-10	x		-10	y	=	-800		
5	x		10	y	=	610		
Add the two equations								
-5	x				=	-190		
/	-5							
x	=	38		Nickels				
plug value of 			x	in (1)				
1	x	+	1	y	=	80		
38		+	1	y	=	80		
			1	y	=	80		-38
			1	y	=	42		
				y	=	42		Dimes
