Question 1177331

Let	x	price of doughnut				0.06			
	y	price of large coffee				0.17			
									
									
2.00	x	+	6.00	y	=	6.58			
									
									
6.00	x	+	2.00	y	=	5.82	.............2		
Eliminate 	y								
multiply (1)by		1.00							
Multiply (2) by		-3.00							
2.00	x		6.00	y	=	6.58			
-18.00	x		-6.00	y	=	-17.46			
Add the two equations									
-16.00	x				=	-10.88			
/	-16.00								
x	=	0.68							
plug value of			x	in (1)					
2.00	x	+	6.00	y	=	6.58			
1.36		+	6.00	y	=	6.58			
			6.00	y	=	5.22			
				y	=	0.87			
Ans	x	=	0.68						
	y	=	0.87						
	$0.68	price of doughnut							
	$0.87	price of large coffee
