Question 519890
x-y=62

5y-2x=155

1	x		-1	y	=	62	.............1	
-2	x	+	5	y	=	155	.............2	
Eliminate y								
multiply (1)by 		5						
Multiply (2) by		1						
5	x		-5	y	=	310		
-2	x		5	y	=	155		
Add the two equations								
3	x				=	465		
/	3							
x	=	155			      			
plug value of 			x	in (1)				
1	x	+	-1	y	=	62		
155		+	-1	y	=	62		
			-1	y	=	62		-155
			-1	y	=	-93		
				y	=	93.00		
155 ,93
