What is the solution to this equation?

[tex] x - 16 = 9 [/tex]

A. [tex] x = 25 [/tex]
B. [tex] x = -7 [/tex]
C. [tex] x = 7 [/tex]
D. [tex] x = -25 [/tex]

Answer :

Let's solve the equation step by step:

The given equation is:

[tex]\[ x - 16 = 9 \][/tex]

To solve for [tex]\( x \)[/tex], we need to isolate [tex]\( x \)[/tex] on one side of the equation. We can do this by adding 16 to both sides. This step helps us cancel the -16 on the left side:

1. Start with the equation:
[tex]\[ x - 16 = 9 \][/tex]

2. Add 16 to both sides:
[tex]\[ x - 16 + 16 = 9 + 16 \][/tex]

3. Simplify both sides:
[tex]\[ x = 25 \][/tex]

So, the solution to the equation [tex]\( x - 16 = 9 \)[/tex] is [tex]\( x = 25 \)[/tex].

The correct answer is:

A. [tex]\( x = 25 \)[/tex]
