So therefore: your solution is (x,y) = (2, 13)

where: 
x = 2 
y = 13

Do you understand @John_John ?

anonymous · Answer

im looking over it now

anonymous · Answer

Btw you already had the solution (2,13)? So what exactly were you looking for or wanting to do?

anonymous · Answer

oh i had needed help with that problem well what about y=x+5
                                                                                  3x+y=25

anonymous · Answer

So you want x... 

So divide by 4 on both sides..
