You start from this equation
= 5
This equation is equivalent to
3x + 4 = = 32.
Therefore,
3x = 32 - 4
3x = 28
x = = 9. ANSWER
Solved.

Learn this lesson from my post:
You do not need to change the base of logarithms from 2 to 10.
You do not need to change the base of logarithms, at all.
Do not make excessive operations --- do not make excessive work --- it is only a source for possible errors.
Do not spend your time for nothing.
There is an issue of correct STYLE, also. When you do it, as the other tutor does,
you only demonstrate that you do not know the subject, the logarithms,
and do not know how to solve such problems correctly.
Remember, that a right style is YOUR REPUTATION (!)
