Question 816617
x= 	cost of	dearer ticket						
y=	cost of	cheaper ticket						
 								
112.00	x	+	60.00	y	=	45.60	.............1	
Total value								
96.00	x	+	120.00	y	=	52.80	.............2	
Eliminate	y							
multiply (1)by		-2.00						
Multiply (2) by		1.00						
-224.00	x		-120.00	y	=	-91.20		
96.00	x	+	120.00	y	=	52.80		
Add the two equations								
-128.00	x				=	-38.40		
/	-128.00							
x	=	0.30						
plug value of			x	in (1)				
112.00	x	+	60.00	y	=	45.60		
33.60		+	60.00	y	=	45.60		
			60.00	y	=	45.60		-33.60
			60.00	y	=	12.00		
				y	=	0.20		
x=	0.30		cost of	dearer ticket				
y=	0.20		cost of	cheaper ticket
