Question 695506
x= 	hot dogs							
y=	soda							
Total  sold								
1	x	+	1	y	=	87	.............1	
								
2	x		0.50	y	=	78.50	.............2	
Eliminate	y							
multiply (1)by		-0.50						
Multiply (2) by		1.00						
-0.50	x		-0.50	y	=	-43.50		
2	x	+	0.50	y	=	78.50		
Add the two equations								
1	x				=	35.00		
/	1							
x	=	35.00						
plug value of			x	in (1)				
1	x	+	1	y	=	87		
35		+		y	=	87		
				y	=	87		-35
				y	=	52		
				y	=	52.00		
x=	35		hot dogs					
y=	52		soda
