What is the solution to 3 + 4e^x+1 = 11?
Solution:

To solve for x, Let us subtract 3 from both sides



Let us divide by 4 on both sides



Let us take ln on both sides

So, x+1=ln(2)
To solve for x, Let us subtract 1 from both sides
x+1-1=ln(2) -1
x+0=ln(2)-1
x= ln(2) -1
Answer: Option (A)
x=ln(2)-1
