Question 486194
2	x		-5	y	=	-1	.............1				
-3	y	=	-3		-1	x	---------2				
/	-3	=									
	y	=	1	+	0.33	x					
Substitute y in 		(1)									
2	x		-5	(	1	+	0.33	x	)	=	-1
2	x		-5	+	-1.67	x	=	-1			
2	x		-1.67	x	=	-1	5				
0.33	x	=	4								
/	0.33										
x=	12										
Plug the value of x in (1)											
2	x		-5	y	=	-1					
2	*	12		-5	y	=	-1				
24		-5	y	=	-1						
-5	y	=	-25								
/	-5										
y=	5

10	x	+	3	y	=	8	.............1				
1	y	=	2		-2	x	---------2				
/	1	=									
	y	=	2		-2	x					
Substitute y in 		(1)									
10	x	+	3	(	2		-2	x	)	=	8
10	x	+	6	+	-6	x	=	8			
10	x		-6	x	=	8	-6				
4	x	=	2								
/	4										
x=	0.5										
Plug the value of x in (1)											
10	x	+	3	y	=	8					
10	*	0.5	+	3	y	=	8				
5	+	3	y	=	8						
3	y	=	3								
/	3										
y=	1
