To solve the equation \( x + 7 = -9 \), you need to isolate \( x \). You can do this by subtracting 7 from both sides of the equation:
\[
x + 7 - 7 = -9 - 7
\]
This simplifies to:
\[
x = -16
\]
So the value of \( x \) that makes the equation true is \( -16 \).
The correct answer is:
**A. -16**
\[
x + 7 - 7 = -9 - 7
\]
This simplifies to:
\[
x = -16
\]
So the value of \( x \) that makes the equation true is \( -16 \).
The correct answer is:
**A. -16**
