x		6 cent stamps						
y		8 cent stamps						
							
6	x	+	8	y	=	300	.............1	
								
1	x	+	1	y	=	45	.............2	
Eliminate	y							
multiply (1)by		-1						
Multiply (2) by		8						
-6	x		-8	y	=	-300		
8	x	+	8	y	=	360		
Add the two equations

/	2							
x	=	30						
plug value of			x	in (1)				
6	x	+	8	y	=	300		
180		+	8	y	=	300		
			8	y	=	300		-180
			8	y	=	120		
				y	=	15
