<PRE><B>Question 1202396</B>
Let	x	Number of adult tickets sold				
Let	y	Number of child tickets sold				
						
	Number of tickets equation					
x	+	y	=	120
						
						
3.50	x	+	2.00	y	=	324.00
Eliminate 	y					
multiply (1)by		2				
Multiply (2) by		-1				
2.00	x		2.00	y	=	240.00
-3.50	x		-2.00	y	=	-324.00
Add the two equations						
-1.50	x				=	-84.00
/	-1.50					
x	=	56				
plug value of			x	in (1)		
1.00	x	+	1.00	y	=	120
56.00		+	1.00	y	=	120
			1.00	y	=	64.00
				y	=	64
Ans	x	=	56			
	y	=	64			
	56	Number of adult tickets sold				
	64	Number of child tickets sold		



56*3.5+64*2= 324
