Question 867320
x at 8%

y at 11%

y=3x+38000

y-3x=38000....................(1)

Interest
8%x+11%y=34101
multiply by 100
8x+11y=3410100................(2)

solve (1) & (2)

-3.00	x	+	1.00	y	=	38000.00	.............1	
Total value								
8.00	x	+	11.00	y	=	3410100.00	.............2	
Eliminate	y							
multiply (1)by		-11.00						
Multiply (2) by		1.00						
33.00	x		-11.00	y	=	-418000.00		
8.00	x	+	11.00	y	=	3410100.00		
Add the two equations								
41.00	x				=	2992100.00		
/	41.00							
x	=	72978.05						
plug value of			x	in (1)				
-3.00	x	+	1.00	y	=	38000.00		
-218934.15		+		y	=	38000.00		
				y	=	38000.00	+	218934.15
				y	=	256934.15		
				y	=	256934.15		
x=	72978.05		amount at	8%				
y=	256934.15		amount at	11%
