Question 1111602
Adult	x	tickets								
children	y	tickets								
Equation for tickets										
										
1	x	+	1	y	=	300	.............1			
										
Equation for amount spent										
15	x	+	12.00	y	=	4140	.............2			
Eliminate y										
multiply (1)by		-12.00								
Multiply (2) by		1								
-12.00	x		-12.00	y	=	-3600.00				
15.00		+	12.00	y	=	4140.00				
Add the two equations										
3	x				=	540.00				
/	3									
x	=	180								
plug value of			x	in (1)						
180.00	x	+	1.00	y	=	300.00				
180.00		+	1.00	y	=	300.00				
			1.00	y	=	120.00				
										
										
Adult	180.00	tickets
