Question 1003069

x= 		number of adults						
y=		number of children						
Total comercials								
1.00	x	+	1.00	y	=	92.00	.............1	
Total value								
9.50	x	+	7.75	y	=	837.25	.............2	
Eliminate	y							
multiply (1)by		-7.75						
Multiply (2) by		1.00						
-7.75	x		-7.75	y	=	-713.00		
9.50	x	+	7.75	y	=	837.25		
Add the two equations								
1.75	x				=	124.25		
/	1.75							
x	=	71.00						
plug value of			x	in (1)				
1.00	x	+	1.00	y	=	92.00		
71.00		+		y	=	92.00		
				y	=	92.00		-71.00
				y	=	21.00		
				y	=	21.00		
x=	71		number of adults					
y=	21		number of children
