Hi there!

I believe your answer is:

Here’s why:

Hope this helps you. I apologize if it’s incorrect.  

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the answer is y = 11.54

hope this : )
