To solve the equation [tex]\( x + 15 = 28 \)[/tex], we need to isolate the variable [tex]\( x \)[/tex].
1. Start with the given equation:
[tex]\[
x + 15 = 28
\][/tex]
2. To isolate [tex]\( x \)[/tex], subtract 15 from both sides of the equation. This helps us to get [tex]\( x \)[/tex] by itself on one side:
[tex]\[
x + 15 - 15 = 28 - 15
\][/tex]
3. Simplifying both sides, we get:
[tex]\[
x = 13
\][/tex]
So, the solution to the equation [tex]\( x + 15 = 28 \)[/tex] is [tex]\(\boxed{13}\)[/tex].
By comparing this solution with the provided options, we see that the correct answer is:
B. [tex]\( x = 13 \)[/tex]
