Senior citizens	x	tickets							
regular	y	tickets							
									
1	x	+	1	y	=	65	.............1		
10	x	+	15	y	=	855	.............2		
Eliminate y									
multiply (1)by 		-15							
Multiply (2) by		1							
-15	x		-15	y	=	-975			
10	x	+	15	y	=	855			
Add the two equations									
-5	x				=	-120			
/	-5								
x	=	24   				
plug value of 			x	in (1)					
1	x	+	1	y	=	65			
24		+	1	y	=	65			
			1	y	=	65		-24	
			1	y	=	41			
				y	=	41
