Question 798520
6	x	+	5	y	=	245	.............1				
5	y	=	245	+	-6	x					
/	5	=									
	y	=	49	+	-1.2	x					
4	x	+	3	y	=	155		.....................2			
Substitute y in		(2)									
4	x	+	3	(	49	+	-1.2	x	)	=	155
4	x	+	147	+	-3.6	x	=	155			
4	x		-3.6	x	=	8					
0.4	x	=	8								
/	0.4										
x=	20      										
Plug the value of x in (1)											
6	x	+	5	y	=	245					
6	*	20      	+	5	y	=	245				
120      	+	5	y	=	245						
5	y	=	125      								
/	5										
y=	25
