Have you considered dividing by 3?

zab505 · Answer

Dividing what by 3?

anonymous · Answer

dividing both sides by 3

tkhunny · Answer

I'll take that as a no.

Can you solve this:  3y = 12

zab505 · Answer

y=4

tkhunny · Answer

Why is that different from the problem you presented?  Do the same thing.

zab505 · Answer

D?

tkhunny · Answer

That was quite a leap.  How did you manage that result?

zab505 · Answer

I did as I would with the y=4 problem

tkhunny · Answer

Dividing by 3 resulted in $ln(x) = 3.3$.  Then what?

zab505 · Answer

I solved for x

tkhunny · Answer

In this case, how did you do that?

zab505 · Answer

Calculator

tkhunny · Answer

Sigh.  I suppose.  I had hoped that you would be more communicative.

I have $ln(x) = 3.3$.

Using properties of logarithms, this transforms to $x = e^{3.3}$.

A calculator then provides the numerical result, x = 27.11

Make a better effort to communicate.  It will serve you well.

zab505 · Answer

Sorry about that, but I am very thankful!

tkhunny · Answer

Not a matter of sorry.  That's why some elementary text books try to force students to use "complete sentences".  Learning to communicate is important, too.
