Question 551608
1	x	+	2	y	=	23	.............1
5	x	+	10	y	=	55	.............2
Eliminate y							
multiply (1)by 		-5					
Multiply (2) by		1					
-5	x		-10	y	=	-115	
5	x		10	y	=	55	
Add the two equations							
0	x				=	-60	

this is absurd
so there is no solution to this system. If you draw a graph you will seee that they are parallel lines
