Question 558171
6%--------x
10%---------y

y=x+1000
y-x=1000...........1

6%x+10%y=340
multiply by 100
6x+10y=34000.....2


-1	x	+	1	y	=	1000	.............1	
6	x	+	10	y	=	34000	.............2	
Eliminate y								
multiply (1)by 		-10						
Multiply (2) by		1						
10	x		-10	y	=	-10000		
6	x		10	y	=	34000		
Add the two equations								
16	x				=	24000		
/	16							
x	=	1500			
plug value of 			x	in (1)				
-1	x	+	1	y	=	1000		
-1500		+	1	y	=	1000		
			1	y	=	1000	+	1500
			1	y	=	2500		
				y	=	2500
