Alice solved the following equation:

\[
-18 - 3x = 12
\]
\[
-3x = 6
\]
\[
x = -2
\]

Which of the following statements is true?

A. Alice is correct.

B. The 6 should be 30 in step two.

C. The 6 should be -6 in step two.

D. The 6 should be -4 in step two.

so -18-3x=12 to get to -3x=12+-somthing we must add 18 to both sides or +18-18-3x=12+18 -3x=30 so 'The 6 should be 30 in step 2' is correct x=-10

The 6 should be 30 in step 2 because you have to add 18 to both sides to cancel out the -18.

Alice made a mistake in solving the equation − 18 − 3 x = 12 . Instead of resulting in − 3 x = 6 , it should result in − 3 x = 30 . Therefore, the correct answer is option B.
