x= 	Amount invested at	5.00%							
y=	Amount invested at	6.00%	
5%x+6%y=630
multiply by 100						
 									
5	x	+	6	y	=	63000	.............1		
			y-x 	=	5000	.............2		
Eliminate	y								
multiply (1)by		-1							
Multiply (2) by		6							
-5	x		-6	y	=	-63000			
-6	x	+	6	y	=	30000			
Add the two equations									
-11	x				=	-33000			
/	-11								
x	=	3000      							
plug value of			x	in (1)					
5	x	+	6	y	=	63000			
15000		+	6	y	=	63000			
			6	y	=	63000		-15000	
			6	y	=	48000			
				y	=	8000			
x=	3000		Amount invested at	5%					
y=	8000		Amount invested at	6%

----------------

x= 	Number of	student tickets						
y=	Number of	non student tickets						
 								
1	x	+	1	y	=	3000	.............1	
								
9	x	+	15	y	=	36000	.............2	
Eliminate	y							
multiply (1)by		-15						
Multiply (2) by		1						
-15	x		-15	y	=	-45000		
9	x	+	15	y	=	36000		
Add the two equations								
-6	x				=	-9000		
/	-6							
x	=	1500      						
plug value of			x	in (1)				
1	x	+	1	y	=	3000		
1500		+		y	=	3000		
				y	=	3000		-1500
				y	=	1500		
				y	=	1500		
x=	1500		Number of	student tickets				
y=	1500		Number of	non student tickets
