I have already done that in the second question where they tell you to use NewtonÂ´s method. But the first question is: Show that we can find the value of a, solving the equation e^x+x-3=0.

The task is:
The tangent to the curve \(\displaystyle y=e^{2-x} \) in \(\displaystyle x=2 \) cuts the curve \(\displaystyle y=e^x \) in a point where x=a.

Without understanding the exact language of the problem, I cannot be sure my suggestion is even partially relevant. And my Swedish is non-existent so you are on your own in terms of judging how helpful the suggestion is.

In the second question, I used Newton's method to find an approximate value of a, and got 0,792059, that is correct. My problem is that they want us to find the same value, but by solving the equation given over in the first question.
