I need help with 1 more

I don't know what to do for this one either. This stuff is just so confusing.

Evaluate dy/dt for the function at the point.

x^2 ln y = -1 + xe^y; dx/dt = 8, x = 5, y = 1

I don't know what to do for this one either.

Plug in the given value for y. Solve for the value of x.

Return to the original equation. Differentiate implicitly with respect to "t". Then plug in the given values for dx/dt and y, and the value you found (above) for x. Simplify to find dy/dt.

If you get stuck, please reply showing all of your steps.

Thank you.

P.S. to tutors: Yes, it's "them".
