Question 407761
5x-7y=9	.............1	
4x-3y=33.............2	
								
multiply (1)by 					-4			
Multiply (2) by					5			
-20x+28y=-36		
20x-15y=165		
								
Add the two equations								
								
13y=129		
/13					
						
y=9.92			
Plug value of y in 					
5x-7y=9
5x-69.46		=	9
5x=78.46
/5					
x=15.69
