get x by itself
how do you move 5x to the other side

anonymous · Answer

I'm not sure that's why I need help.

precal · Answer

when you move things to the opposite side take its opposite sign
what sign is 5x

anonymous · Answer

I'm not sure if it would be positive or negative. I think the answer would be y = 5x + 4 but I'm not sure. I don't know if the 5x should be positive or negative.

precal · Answer

when a sign is not given or nothing is in front assume that it is positive
what is the opposite of positive

anonymous · Answer

The opposite of positive is obviously negative..

precal · Answer

5x+y=4
-5x      -5x
y=4-5x

precal · Answer

or y =-5x+4

anonymous · Answer

So -5x + 4 would be the correct answer?

precal · Answer

yes but most important do you understand why

anonymous · Answer

Yes because when a sign is not given or nothing is in front of the number just assume that it is positive. Then move onto solving the problem by subtracting by the opposite of the number & that will give you your answer..
