	hamburgers		x 	cost					
	hotdogs	------------	y	cost					
3x+4y=10.............1		
2x+3y=7	.............2		
Eliminate y									
multiply (1)by 		-3							
Multiply (2) by		4							
-9x-12y	=-30			
8x+12y=28			
Add the two equations									
-1x=-2			
/-1								
x=$2 hamburgers			
plug value of x	in (1)					
3x+4y=	10			
6+4y=10
