Question 861739
x= 	number of	Rs. 6 mouse						
y=	number of	Rs. 13 mouse						
 								
1	x	+	1	y	=	50	.............1	
Total value								
6	x	+	13	y	=	433	.............2	
Eliminate	y							
multiply (1)by		-13						
Multiply (2) by		1						
-13	x		-13	y	=	-650		
6	x	+	13	y	=	433		
Add the two equations								
-7	x				=	-217		
/	-7							
x	=	31						
plug value of			x	in (1)				
1	x	+	1	y	=	50		
31		+		y	=	50		
				y	=	50		-31
				y	=	19		
				y	=	19		
x=	31.00		number of	Rs. 6 mouse				
y=	19.00		number of	Rs. 13 mouse
