5x+45=y

5x-6y=-20	.............1				
y=45+5x	---------2				
plug the value of y in (1)											
5x-6(45+	5x)=-20
5x-270-30x=-20			
5x-30x=-20+270				
-25x=250								
/-25										
x=-10										
Plug the value of x in (1)											
5x-6y=-20					
5*-10-6y	=-20				
-50-6y=-20						
-6y=30								
/-6										
y=-5										
											
CHECK
