To find the value of \( 8x \) when \( 2x = -4 \), you first need to solve for \( x \).
1. Start with the equation:
\[
2x = -4
\]
2. Divide both sides by 2 to isolate \( x \):
\[
x = \frac{-4}{2} = -2
\]
Now that you have the value of \( x \), you can find \( 8x \):
\[
8x = 8 \cdot (-2) = -16
\]
Thus, the value of \( 8x \) is \(-16\).
