I have a problem that I could use some help understanding how to solve/answer from a homework sheet. x varies directly with y and inversely with z. x=20 when y=8 and z=4. Find x when y=4 and z=8. Thank you
I am trying to figure this equation out but I am doing it wrong. We do not have a text book to go by.
7x=36+4x
Thanks,
Brandon
