To solve the equation \(-10 - 2x = -8\), follow these steps:
1. **Isolate the term with \(x\)**: Start by adding 10 to both sides of the equation.
\[
-10 - 2x + 10 = -8 + 10
\]
This simplifies to:
\[
-2x = 2
\]
2. **Solve for \(x\)**: Now, divide both sides by -2.
\[
x = \frac{2}{-2} = -1
\]
So, the solution is \(x = -1\).
The correct response is:
- x = −1
- x equals negative 1
