1.2	x		-1	y	=	0	.............1	
3	x	+	2	y	=	7	.............2	
Eliminate y								
multiply (1)by 		2						
Multiply (2) by		1						
2.4	x		-2	y	=	0		
3	x	+	2	y	=	7		
Add the two equations								
5.4	x				=	7		
/	5.4							
x	=	1.30		OR	9/7			
plug value of 			x	in (1)				
1.2	x	+	-1	y	=	0		
1.56		+	-1	y	=	0		
			-1	y	=	0		-1.56
			-1	y	=	-1.56		
				y	=	1.56		OR 14/9
