Question 552429
2	x	+	3	y	=	9	.............1		
3	x	+	4	y	=	5	.............2		
Eliminate y									
multiply (1)by 		-4							
Multiply (2) by		3							
-8	x		-12	y	=	-36			
9	x		12	y	=	15			
Add the two equations									
1	x				=	-21			
/	1								
x	=	-21			
plug value of 			x	in (1)					
2	x	+	3	y	=	9			
-42		+	3	y	=	9			
			3	y	=	9	+	42	
			3	y	=	51			
				y	=	17
