Question 447231
8x+4y=4	.............1	
rewrite the second equation			
4y=38+9x---------2				
/4									
y=9.5+2.25x					
substitute the value of y in (1)											
8x+4(9.5+2.25x)=4
8x+38+9x=4			
8x+9x=4-38				
17x=-34								
/17										
x=-2										
Plug the value of x in (1)											
8x+4y=4					
8*-2+4y=4				
-16+4y=4						
4y=20								
/4										
y=5
