Question 731616
x= 	pounds of	coffee type I							
y=	pounds of	coffee type II							
 									
-2.00	x	+	1.00	y	=	10.00	.............1		
Total value									
6.25	x	+	5.40	y	=	190.40	.............2		
Eliminate	y								
multiply (1)by		-5.40							
Multiply (2) by		1.00							
10.80	x		-5.40	y	=	-54.00			
6.25	x	+	5.40	y	=	190.40			
Add the two equations									
17.05	x				=	136.40			
/	17.05								
x	=	8.00							
plug value of			x	in (1)					
-2.00	x	+	1.00	y	=	10.00			
-16.00		+		y	=	10.00			
				y	=	10.00	+	16.00	
				y	=	26.00			
				y	=	26.00			
x=	8.00		pounds of	coffee type I					
y=	26.00		pounds of	coffee type II
