Answer :
To solve the equation [tex]\( x - 16 = 9 \)[/tex], we need to isolate [tex]\( x \)[/tex] on one side of the equation. Here's how you can do it step-by-step:
1. Identify the operation: The equation is [tex]\( x - 16 = 9 \)[/tex]. The operation involving [tex]\( x \)[/tex] is subtraction (subtracting 16).
2. Inverse the operation: To isolate [tex]\( x \)[/tex], we need to do the opposite (inverse) operation. Since 16 is being subtracted, we will add 16 to both sides of the equation.
3. Add 16:
[tex]\[
x - 16 + 16 = 9 + 16
\][/tex]
4. Simplify:
[tex]\[
x = 25
\][/tex]
So, the solution to the equation [tex]\( x - 16 = 9 \)[/tex] is [tex]\( x = 25 \)[/tex].
Thus, the correct answer is B. [tex]\( x = 25 \)[/tex].
