Question 668715
x	Adult tickets							
y	Student stickets							
Total tickets sold								
x+y	=	427.00	.............1	
Value of tickets								
8.50	x	+	6.50	y	=	3,263.50	.............2	
Eliminate	y							
multiply (1)by		-6.50						
Multiply (2) by		1.00						
-6.50	x		-6.50	y	=	-2,775.50		
8.50	x	+	6.50	y	=	3,263.50		
Add the two equations								
2.00	x				=	488.00		
/	2.00							
x	=	244.00						
plug value of			x	in (1)				
x	+y	=	427.00		
244.00		+		y	=	427.00		
				y	=	427.00-244
				y	=	183.00		
				y	=	183.00		
	244		Adult tickets					
	183	Student stickets
