Question 437118

Rewrite the equations

-1x+3y=	4	.............1				
											
2y=24-2x---------2				
/2									
y=12-x					
Plug the value of y in (1)											
-x+3(12-x)=4
-x+36-3x=4			
-x-3x=4-36				
-4x=-32								
/-4										
x=8										
Plug the value of x in (1)											
-x+3y=4					
-1*8+3y=4				
-8+3y=4						
3y=12								
/3										
y=4
