Question 1027501
x= 	number of	adult tickets							
y=	number of	child tickets							
Total  sold									
1.00	x	+	1.00	y	=	500.00	.............1		
Total value									
7.00	x	+	5.00	y	=	2970.00	.............2		
Eliminate	y								
multiply (1)by		-5.00							
Multiply (2) by		1.00							
-5.00	x		-5.00	y	=	-2500.00			
7.00	x	+	5.00	y	=	2970.00			
Add the two equations									
2.00	x				=	470.00			
/	2.00								
x	=	235.00							
plug value of			x	in (1)					
1.00	x	+	1.00	y	=	500.00			
235.00		+		y	=	500.00			
				y	=	500.00		-235.00	
				y	=	265.00			
				y	=	265.00			
x=	235.00		number of	adult tickets					
y=	265.00		number of	child tickets
