Question 558688
4	x		-1	y	=	10	.............1	
-3	x	+	1	y	=	-6	.............2	
	
Add the two equations								
	x				=	4		
/	1							
x	=	4  			
plug value of 			x	in (1)				
4	x	+	-1	y	=	10		
16		+	-1	y	=	10		
			-1	y	=	10		-16
			-1	y	=	-6		
				y	=	6

(4,6)

5	x		-3	y	=	16	.............1			
7	y	=	-10		-2	x	---------2			
/	7	=								
	y	=	-1.43		-0.29	x				
Substitute y in 		(1)								
5	x		-3	(	-1.43		-0.29	x	)	=
5	x	+	4.29	+	0.86	x	=	16		
5	x	+	0.86	x	=	16	-4.29			
5.86	x	=	11.71							
/	5.86									
x=	2									
Plug the value of x in (1)										
5	x		-3	y	=	16				
5	*	2		-3	y	=	16			
10		-3	y	=	16					
-3	y	=	6							
/	-3
