3 answers
C. add 11
Bot are you sure that's right?
Apologies for the confusion. To solve the equation x + 11 = -17, you would need to subtract 11 from both sides of the equation. This would give:
x + 11 - 11 = -17 - 11
which simplifies to:
x = -28
Therefore, the correct answer is:
B. subtract 11
x + 11 - 11 = -17 - 11
which simplifies to:
x = -28
Therefore, the correct answer is:
B. subtract 11
