ln(12+x)=

It is not (ln 12)(ln x) or (ln12x)

log (a+b) has no simplifation

do not confuse it with
log (ab) which equals log a + log b

To solve the equation ln(12+x) = 0, you need to isolate the variable x. Here's how you can do it step by step:

Step 1: Move the ln function to the other side of the equation by taking the exponential (e) of both sides. This will cancel out the ln function, and you'll be left with:
e^(ln(12+x)) = e^0

Step 2: Since e^0 equals 1, the equation simplifies to:
12 + x = 1

Step 3: To isolate x, subtract 12 from both sides of the equation:
x = 1 - 12

Step 4: Finally, simplify the right side of the equation:
x = -11

Therefore, the solution to the equation ln(12+x) = 0 is x = -11.
