Question

when solving the equation −12(x+10)=−3 identify the operation that should be done first.(1 point)

Answer 1

which one is right
subtract 10 subtract 10 multiply by −2 multiply by negative 2 divide by −2 divide by negative 2 add 10

Answer 2

To solve the equation \(-12(x + 10) = -3\), the first operation that should be done is to isolate the term involving \(x\). This involves dealing with the multiplication by \(-12\).

You can achieve this by dividing both sides of the equation by \(-12\):

\[
x + 10 = \frac{-3}{-12}
\]

This simplifies the process by eliminating the multiplication. So, the operation that should be done first is to divide both sides by \(-12\).

Answer 3

To solve the equation \(-12(x + 10) = -3\), the correct first operation would be to **divide by -12** (which corresponds to the option "divide by -2" since dividing by -12 would involve simplifying by -6 in this context). However, let's break it down using your provided choices, assuming we need an operation that relates to the context:

In this case, once you've factored out the equation, an immediate way to simplify is generally to isolate \(x\):

- If you look at how to isolate \(x\) directly without rewriting the equation:
1. The term \(10\) is added to \(x\), so you would eventually want to **subtract 10** from both sides after dealing with the multiplication side.

However, if you are looking for the very first operation in terms of handling the equation (in practical steps), **you would divide by \(-12\)**, and it involves eventually moving towards a form where you isolate \(x\) by subtracting 10 afterward.

Thus, in the context given, if focusing on immediate steps:
- The **operation that would logically come first to make it simpler** is **"divide by -12"**, but if you must follow through with handled operations in subsequent steps, you will get to **"subtract 10"** next as part of isolating \(x\).

Make your choice based on this guidance regarding the immediate transformation or subsequent steps.
