The right answer is Option D.
Step-by-step explanation:
Steps done by Brad;
[tex]-3(2+w)=-45\\2+w=-15\\w=-17[/tex]
Brad made the error in first step where he divided both sides by 3; but one left side, he did not put the negative sign.
In order to correct his error, Brad should divide -45 by -3 to get 15.
Therefore;
[tex]-3(w+2)=-45\\w+2=\frac{-45}{-3}\\w+2=15[/tex]
Thus,
Divide -45 by -3 to get 15.
The right answer is Option D.
