<PRE><B>Question 585215</B>
c+f=152.............(1)

c= 5+6f
c-6f=5..............(2)

c	+	1	f	=	152	.............1	
c		-6	f	=	5	.............2	
Eliminate	y							
multiply (1)by		6						
Multiply (2) by		1						
6	c		6	f	=	912		
1	c		-6	f	=	5		
Add the two equations								
7	c				=	917		
/	7							
c	=	131      						
plug value of			x	in (1)				
1	c	+	f	=	152		
131    		+	f	=	152		
			f	=	152-131      
			f	=	21      		
			f	=	21
