PLEASE HELP ME

erik [133]

Answer:

$x=\frac{-5+ln9}{3}$ which appears to be from the list x=ln9-5/3

Step-by-step explanation:

We take the natural logarithm of both sides as the inverse operation to an exponent on e. This allows us to use log rules to rearrange the problem.

$e^{3x+5}=9\\lne^{3x+5}=ln9 \\(3x+5)lne=ln9$

We know that as inverse operations, ln e =1.

$(3x+5)(1)=ln9\\3x+5=ln9\\3x=-5+ln9\\\frac{3x}{3}=\frac{-5+ln9}{3}$

$x=\frac{-5+ln9}{3}$
