7 is her number. 

Answer:

Her number is 7.

Step-by-step explanation:

Thu wants to play guess my number.

Let her number be 'n'.

As per Thu's statement "When I triple my number and add five, I get 26."

The expression will be

3x + 5 = 26

3x = 26 - 5

3x = 21

x = [tex]\frac{21}{3}[/tex]

x = 7

Her number is 7.
