Question

Number 9 (What should Brad do to correct the error that he made?)

Answer 1

The right answer is Option D.

Step-by-step explanation:

Steps done by Brad;

$-3(2+w)=-45\\2+w=-15\\w=-17$

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;

$-3(w+2)=-45\\w+2=\frac{-45}{-3}\\w+2=15$

Thus,

Divide -45 by -3 to get 15.

The right answer is Option D.
