Question 855910
x= 	cost per	gallon						
y=	cost per	brush						
 								
8.00	x	+	3.00	y	=	152.50	.............1	
Total value								
6.00	x	+	2.00	y	=	113.00	.............2	
Eliminate	y							
multiply (1)by		-2.00						
Multiply (2) by		3.00						
-16.00	x		-6.00	y	=	-305.00		
18.00	x	+	6.00	y	=	339.00		
Add the two equations								
2.00	x				=	34.00		
/	2.00							
x	=	17.00						
plug value of			x	in (1)				
8.00	x	+	3.00	y	=	152.50		
136.00		+	3.00	y	=	152.50		
			3.00	y	=	152.50		-136.00
			3.00	y	=	16.50		
				y	=	5.50		
x=	17.00		cost per	gallon				
y=	5.50		cost per	brush
