Question 837602
x= 	number of	orchestra seats						
y=	number of	balcony seats						
 								
1	x	+	1	y	=	500	.............1	
Total value								
45	x	+	30	y	=	18,000	.............2	
Eliminate	y							
multiply (1)by		-30						
Multiply (2) by		1						
-30	x		-30	y	=	-15,000		
45	x	+	30	y	=	18,000		
Add the two equations								
15	x				=	3,000		
/	15							
x	=	200						
plug value of			x	in (1)				
1	x	+	1	y	=	500		
200		+		y	=	500		
				y	=	500		-200
				y	=	300		
				y	=	300		
x=	200.00		number of	orchestra seats				
y=	300.00		number of	balcony seats
