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.
