Question 700285
x= 	number of child tickets							
y=	number of adult tickets							
Total  sold								
1.00	x	+	1.00	y	=	150.00	.............1	
Total value								
4.75	x	+	7.50	y	=	891.25	.............2	
Eliminate	y							
multiply (1)by		-7.50						
Multiply (2) by		1.00						
-7.50	x		-7.50	y	=	-1125.00		
4.75	x	+	7.50	y	=	891.25		
Add the two equations								
-2.75	x				=	-233.75		
/	-2.75							
x	=	85.00						
plug value of			x	in (1)				
1.00	x	+	1.00	y	=	150.00		
85.00		+		y	=	150.00		
				y	=	150.00		-85.00
				y	=	65.00		
				y	=	65.00		
x=	85		number of child tickets					
y=	65		number of adult tickets
