Question 553642
white			x	numbers			
yellow			y	numbers			
							
1	x	+	1	y	=	21	.............1
11.95	x	+	13.5	y	=	268	.............2
Eliminate y							
multiply (1)by 		13.5					
Multiply (2) by		-1					
13.5	x		13.5	y	=	283.5	
-11.95	x		-13.5	y	=	-268	
Add the two equations							
1.55	x				=	15.5	
/	1.55						
x	=	10		
plug value of 			x	in (1)			
1	x	+	1	y	=	21	
10		+	1	y	=	21	
			1	y	=	21	
			1	y	=	11	
				y	=	11
