For what values of x does the function y=2x+13 take on a positive value? a negative value?

Hello,

The  answer is x= y-13 / 2 ( everything after the x= is a  fraction)

How to solve;

Start by subtracting 13 from both sides of y=2x+13, we do this to get the x on 1 side

So now we have y-13=2x

Next divide both sides by 2, we do this to get x by it self.

y-13/2=x

Now we flip the problem and there you have it!

Edit: The x does not have a Pos or neg value, The only way to know what x is, is to solve for x.
