Question 552869
-2x-9y=	-25	.............1		
-4x-9y	=-23	.............2		
Eliminate y									
multiply (1)by 		-1							
Multiply (2) by		1							
2x+9y=	25			
-4x-9y=	-23			
Add the two equations									
-2x=	2			
/	-2								
x	=	-1 				
plug value of 			x	in (1)					
-2	x	+	-9	y	=	-25			
2		+	-9	y	=	-25			
			-9	y	=	-25-2	
			-9	y	=	-27			
				y	=	3
