The given equation is

$3+ 4e^{x+1} = 11$

And we have to solve for x .

First we subtract 3 to both sides, to get rid of 3 and move it to right side, that is

$4e^{x+1} = 8$

Now we need to get rid of 4, and for that , we divide both sides by 4, that is

$e^{x+1} = 2$

Now we need to get rid of e, and for that, we take natural log ln to both sides,that is

x+1= ln(2)

The final step is to subtract 1, and we will get

x = ln(2) -1

Correct option is the first option .
