By def. of the derivative, we have for y = ln(x),



Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as


Recall that the constant e is defined by the limit,

Then in our limit, we end up with

In Mathematica, use

it is the last one before the time
Answer:
x=1, y=4. (1, 4).
Step-by-step explanation:
y=4x
x+y=5
----------
x+4x=5
5x=5
x=5/5
x=1
