Question 724124
x= 	number of  student tickets							
y=	number of guest tickets							
 								
1	x	+	1	y	=	300	.............1	
Total value								
150	x	+	350	y	=	75000	.............2	
Eliminate	y							
multiply (1)by		-350						
Multiply (2) by		1						
-350	x		-350	y	=	-105000		
150	x	+	350	y	=	75000		
Add the two equations								
-200	x				=	-30000		
/	-200							
x	=	150						
plug value of			x	in (1)				
1	x	+	1	y	=	300		
150		+		y	=	300		
				y	=	300		-150
				y	=	150		
				y	=	150		
x=	150		number of  student tickets					
y=	150		number of guest tickets
