Question 490532
2	x	+	5	y	=	33.3	.............1	
3	x		-10	y	=	38	.............2	
Eliminate y								
multiply (1)by 		2						
Multiply (2) by		1						
4	x		10	y	=	66.6		
3	x		-10	y	=	38		
Add the two equations								
7	x				=	104.6		
/	7							
x	=	14.94			
plug value of 			x	in (1)				
2	x	+	5	y	=	33.3		
29.89		+	5	y	=	33.3		
			5	y	=	33.3		-29.89
			5	y	=	3.41		
				y	=	0.68
