Question 730909
x= 	number of  	adult tickets						
y=	number of 	child tickets						
 								
1.00	x	+	1.00	y	=	145.00	.............1	
Total value								
7.50	x	+	4.00	y	=	790.00	.............2	
Eliminate	y							
multiply (1)by		-4.00						
Multiply (2) by		1.00						
-4.00	x		-4.00	y	=	-580.00		
7.50	x	+	4.00	y	=	790.00		
Add the two equations								
3.50	x				=	210.00		
/	3.50							
x	=	60.00						
plug value of			x	in (1)				
1.00	x	+	1.00	y	=	145.00		
60.00		+		y	=	145.00		
				y	=	145.00		-60.00
				y	=	85.00		
				y	=	85.00		
x=	60		number of  	adult tickets				
y=	85		number of 	child tickets
