<PRE><B>Question 474504</B>
4	x	+	3	y	=	3	.............1		
5	x		-9	y	=	144	.............2		
									
multiply (1)by 		3							
Multiply (2) by		1							
12	x	+	9	y	=	9			
5	x	+	-9	y	=	144			
Add the two equations									
17	x				=	153			
/	17								
x	=	9							
plug value of 			x	in (1)					
4	x	+	3	y	=	3			
36		+	3	y	=	3			
			3	y	=	3		-36	
			3	y	=	-33			
				y	=	-11
