I don't really know how to type this, but here it goes: log(base5) 4-log(base5) (x+3)= log(base5) 3?

    \[log_5(4)-log_5(x+3)=log_5(3)\]

    \[log_5(4)-log_5(3)=log_5(x+3)\] \[log_5(\frac{4}{3})=log_5(x+3)\] \[\frac{4}{3}=x+3\]

    only log step was using \[log(A)-log(B)=log(\frac{A}{B})\] from right to left.

    oh i just added \[log_5(x+3)\] to both sides so it would be positive. easier that way

    added \[log_5(x+3)\] to both sides and subtracted \[log_5(3)\] from both sides so i had the variable by itself on one side.
