It looks like this post was victim to the same issue I encountered in one of my posts: HTML encoding thinking that < and > signs were tags. Your post is currently illegible. Could you please post again, and check the "Disable HTML in this post" so that it posts correctly?

Thanks!

Hi there,

I think there is still a typo in the problem. When I try to solve for e given statement 1, this is what I get:

4(e-1) = (4e) – 600 (what you have posted)
4e - 4 = 4e - 600
-4 = -600 .... which is clearly false

Please take another look at the problem and see if something was entered incorrectly. Thanks,

Tatiana
