Question 549651
dimes ----x
quarters --y

x+y=40
10x+25y=595

	x	numbers	dimes				
	y	numbers	quarters				
							
x	+y=40	.............1
10	x	+	25	y	=	595	.............2
Eliminate 	y						
multiply (1)by 		-25					
Multiply (2) by		1					
-25	x		-25	y	=	-1000	
10	x	+	25	y	=	595	
Add the two equations							
-15	x				=	-405.00	
/	-15						
x	=	27      					
plug value of 			x	in (1)			
1	x	+		y	=	40	
27		+		y	=	40	
			y	=	40	
				y	=	13	
				y	=	13      	
dimes		27    					
quarters	13
