Question 536940
multiply first equation by 10
second equation by 100

3    	x	+	2	y	=	40	.............1	
104	x	+	50	y	=	100	.............2	
Eliminate 	y							
multiply (1)by 		-25						
Multiply (2) by		1						
-75	x		-50	y	=	-1000		
104	x	+	50	y	=	100		
Add the two equations								
29	x				=	-900		
/	29							
x	=	-31.03						
plug value of 			x	in (1)				
3    	x	+	2	y	=	40		
-93.1		+	2	y	=	40		
			2	y	=	40	+	93.1
			2	y	=	133.1		
				y	=	66.55
