Question 539738
2    	x		-4	y	=	5	.............1	
3	x	+	2	y	=	6	.............2	
Eliminate 	y							
multiply (1)by 		1						
Multiply (2) by		2						
2	x		-4	y	=	5		
6	x	+	4	y	=	12		
Add the two equations								
8	x				=	17		
/	8							
x	=	2.13						
plug value of 			x	in (1)				
2    	x	+	-4	y	=	5		
4.25		+	-4	y	=	5		
			-4	y	=	5		-4.25
			-4	y	=	0.75		
				y	=	-0.19		
They have only one solution ( 2.13,-0.19)
