Question 778174
x= 	Number of	gate tickets						
y=	Number of	students						
 								
1.00	x	+	1.00	y	=	770.00	.............1	
Total value								
0.50	x		0.25	y	=	228.00	.............2	
Eliminate	y							
multiply (1)by		0.25						
Multiply (2) by		-1.00						
0.25	x		0.25	y	=	192.50		
-0.50	x		-0.25	y	=	-228.00		
Add the two equations								
-0.25	x				=	-35.50		
/	-0.25							
x	=	142.00						
plug value of			x	in (1)				
1.00	x	+	1.00	y	=	770.00		
142.00		+		y	=	770.00		
				y	=	770.00		-142.00
				y	=	628.00		
				y	=	628.00		
x=	142		Number of	gate tickets				
y=	628		Number of	students
