7	x	+	5	y	=	-6	.............1			
4	x	+	3	y	=	-4	.............2			
Eliminate y										
multiply (1)by 		-3								
Multiply (2) by		5								
-21	x	-15	y	=	18					
20	x	15	y	=	-20					
Add the two equations										
-1	x				=	-2				
/	-1									
x	=	2  					
plug value of 			x	in (1)						
7	x	+	5	y	=	-6				
14		+	5	y	=	-6				
			5	y	=	-6		-14		
			5	y	=	-20				
				y	=	-4
