To solve the equation \( -12(x + 10) = -3 \), the first operation you would need to perform is to divide both sides of the equation by \(-12\) to isolate the term \( (x + 10) \).
Therefore, you should first:
divide by −12
However, since this option is not listed, the initial expression \( (x + 10) \) must be handled correctly. The operations listed (subtract 10, divide by -2, etc.) do not directly lead to the first step required to isolate \( x \).
In context, if you intended to focus solely on the contents of the parentheses, you might consider adding or subtracting from that portion of the equation, but the first correct move mathematically involves changing the whole equation by dividing.
If I had to choose one of the provided options related to operations applied to \( x + 10 \) specifically, and there is none that directly addresses dividing by -12, I would clarify that you'd want to isolate \( x + 10 \) by first correcting the operation that leads towards that goal.
In summary, the first and most correct action when solving the provided equation as a whole is to divide by \(-12\).
