Question 486213
9	x		-8	y	=	10	.............1				
1	y	=	3		-1	x	---------2				
/	1	=									
	y	=	3		-1	x					
Substitute y in 		(1)									
9	x-8	(3-x)	=	10
9	x		-24	+	8	x	=	10			
9	x	+	8	x	=	10	24				
17	x	=	34								
/	17										
x=	2										
Plug the value of x in (1)											
9	x		-8	y	=	10					
9	*	2		-8	y	=	10				
18		-8	y	=	10						
-8	y	=	-8								
/	-8										
y=	1
