Answer :
To solve the equation [tex]\( x + 7 = -9 \)[/tex], we need to find the value of [tex]\( x \)[/tex] that makes the equation true.
1. Start with the given equation:
[tex]\[
x + 7 = -9
\][/tex]
2. To isolate [tex]\( x \)[/tex], subtract 7 from both sides of the equation:
[tex]\[
x + 7 - 7 = -9 - 7
\][/tex]
3. Simplify both sides:
[tex]\[
x = -16
\][/tex]
Now we have the potential answer: [tex]\( x = -16 \)[/tex].
Let's verify by substituting this value back into the original equation to ensure it satisfies the equation:
- Substitute [tex]\( x = -16 \)[/tex] into the equation:
[tex]\[
-16 + 7 = -9
\][/tex]
- Simplify:
[tex]\[
-9 = -9
\][/tex]
This is a true statement, so [tex]\( x = -16 \)[/tex] is the correct solution.
Thus, the value of [tex]\( x \)[/tex] that makes the equation true is:
- A. -16
