6	x		-3	y	=	75	.............1		
5	x	+	7	y	=	23	.............2		
Eliminate y									
multiply (1)by 		7							
Multiply (2) by		3							
42	x		-21	y	=	525			
15	x		21	y	=	69			
Add the two equations									
57	x				=	594			
/	57								
x	=	10.42		OR	198/19				
plug value of 			x	in (1)					
6	x	+	-3	y	=	75			
62.53		+	-3	y	=	75			
			-3	y	=	75		-62.53	
			-3	y	=	12.47			
				y	=	-4.16		OR	-25/6
