Question 786982
7    	x	+	6    	y	=	-10    	.............1				
6    	y	=	-10    	+	-7    	x					
/	6    	=									
	y	=	-5/3	+	-1 1/6	x					
-8    	x	+	1    	y	=	36    		.....................2			
Substitute y in		(2)									
-8    	x	+	1    	(	-1 2/3	+	-1 1/6	x	)	=	36    
-8    	x	+	-5/3	+	-7/6	x	=	36    			
-8    	x		-7/6	x	=	113/3					
-55/6	x	=	113/3								
/	-55/6										
x=	-37/9										
Plug the value of x in (1)											
7    	x	+	6    	y	=	-10    					
7    	*	-37/9	+	6    	y	=	-10    				
-115/4	+	6    	y	=	-10    						
6    	y	=	75/4								
/	6    										
y=	25/8
