In keeping with the QuACK goal of sharing exemplary work from the KnowItNow24x7 librarians, the following is an email transaction answered by the leave-a-message answering librarians. This month we recognize Kathy Fisher at Ursuline College.

This is a great example of utilizing online resources and alternative ways of getting information to the patron. Kathy not only provided the link to Wolfram|Alpha, but also screenshots of the patron's problems entered into the site itself. Kathy is not tutoring in math but simply pointing to an online source that can provide the answer. Good thinking and nice work, Kathy!

Hello,

This email is in response to your recent question to KnowItNow24x7, Ohio's statewide online reference service.

I think you are asking to solve two problems:
problem 1: -4/5x-7.2=0
problem 2: 0=2.1-7/8x

I attached the solutions I found using this website:
http://www.wolframalpha.com/

I hope this information helps answer your question. Thank you for using KnowItNow24x7.
