Question 465027
5x-3	y=8	.............1		
-5x+y=4	.............2		
									
multiply (1)by 		1							
Multiply (2) by		3							
5	x		-3	y	=	8			
-15	x		3	y	=	12			
Add the two equations									
-10	x				=	20			
/	-10								
x	=	-2							
plug value of 			x	in (1)					
5	x	+	-3	y	=	8			
-10		+	-3	y	=	8			
			-3	y	=	8	+	10	
			-3	y	=	18			
				y	=	-6
