Question 429848
6x+y=46	.............1		
6x-y=38	.............2		
Eliminate y									
6	x			y	=	46			
6	x		-	y	=	38			
Add the two equations									
12	x				=	84			
/	12								
x	=	7    					
plug value of 			x	in (1)					
6	x	+	1	y	=	46			
42		+	1	y	=	46			
			1	y	=	46	+	-42	
			1	y	=	4			
				y	=	4    	
(7,4) is the solution
