Question 769337
x= 	Coffee	cases						
y=	Tea	cases						
 	First condition -number of cases							
1	x	+	1	y	=	250	.............1	
Total value								
12	x	+	8	y	=	2600	.............2	
Eliminate	y							
multiply (1)by		-8						
Multiply (2) by		1						
-8	x		-8	y	=	-2000		
12	x	+	8	y	=	2600		
Add the two equations								
4	x				=	600		
/	4							
x	=	150						
plug value of			x	in (1)				
1	x	+	1	y	=	250		
150		+		y	=	250		
				y	=	250		-150
				y	=	100		
				y	=	100		
x=	150		Coffee	cases				
y=	100		Tea	cases
