Answer:
C 
Step-by-step explanation:
The given logarithmic equation is:

We rewrite in exponential form; to get;

We rewrite the LHS as a certain natural number exponent 4.

The exponents are the same, hence the bases must also be the same.



Divide both sides by 3;

The correct answer is C
I really, really don't like this question. People have preferences in solving quadratics. I would personally use, and would encourage anyone to use the quadratic equation. That's because completing the square would get excessively fractional, graphically doesn't even work because the solutions are imaginary, and differentiating it wouldn't be necessary, as there are no irrational numbers (except i, which is just imaginary). So, in short, quadratic equation because you can't get anything graphically, the answers are ugly fractions, and you can actually use that method.
2 over 7 or how ever many options are in the same row.
7/4 = (4 + 3)/4 = 4/4 + 3/4 = 1 + 3/4 =
1 3/4

Move variable to the left. -w= -10+ 4W
-w-4W =-10
Collect like terms
-5w=-10 divide both sides by 5
