Answer :

To find the value of [tex]\( x \)[/tex] that makes the equation [tex]\( x + 7 = -9 \)[/tex] true, we can solve the equation using simple algebra.

1. Start with the given equation:

[tex]\[
x + 7 = -9
\][/tex]

2. Subtract 7 from both sides to solve for [tex]\( x \)[/tex]:

- This step helps in isolating [tex]\( x \)[/tex] on one side of the equation.
[tex]\[
x + 7 - 7 = -9 - 7
\][/tex]

- Simplifying both sides, we get:
[tex]\[
x = -16
\][/tex]

3. Conclusion:

The value of [tex]\( x \)[/tex] that makes the equation true is [tex]\(-16\)[/tex].

Therefore, the correct answer is A. -16.
