Which number(s) below belong to the solution set of the equation? Check all that apply.
x + 12 = 13
D A. 13
B. 312
O C. 14
O D. O
O E. 1
F. 25

the answer is b

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

is their an equation anywhere i can take a   look at it and see if i am right.
