Question 614314
7	x	+	6	y	=	30	.............1	
								
9	x		-8	y	=	15	.............2	
Eliminate	y							
multiply (1)by		4						
Multiply (2) by		3						
28	x		24	y	=	120		
27	x		-24	y	=	45		
Add the two equations								
55	x				=	165		
/	55							
x	=	3.00						
plug value of			x	in (1)				
7	x	+	6	y	=	30		
21		+	6	y	=	30		
			6	y	=	30		-21
			6	y	=	9		
				y	=	1.50	

(3,1.5) is the solution of the system
