Question 681439
Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	9.00%		per annum	------------	Amount invested = y	
Total=	17000					
				
Part I	8.00%		per annum	---x		
Part II	9.00%		per annum	---y		
Total investment						
x+y=	17000	-------------1	
Interest on both investments						
8.00%	x	=	9.00%		
Multiply by		100				
8	x	=	9	y
8x-9y=0	--------2


1	x	+	1	y	=	17000	.............1	
								
8	x		-9	y	=	0	.............2	
Eliminate	y							
multiply (1)by		9						
Multiply (2) by		1						
9	x		9	y	=	153000		
8	x		-9	y	=	0		
Add the two equations								
17	x				=	153000		
/	17							
x	=	9000						
plug value of			x	in (1)				
1	x	+	1	y	=	17000		
9000		+		y	=	17000		
				y	=	17000		-9000
				y	=	8000		
				y	=	8000		
x=	9000	Part I					
y=	8000	Part II
