help me with this algebra.(i put a Picture with it)

Answer:
no Luke is not correct.
Step-by-step explanation:
[tex]4r + 5 + 2r \\ colecting \: like \: terms \: \\ 4r + 2r + 5 \\ 6r + 5[/tex]
Answer:
Luke is wrong because 4r + 5 + 2r = 6r+5.
You can only add numbers with the same variable, 4r and 2r have the same variable so they can be added while 5 does not have a variable, this means it cannot be added to 4r and 2r.
Step-by-step explanation:
4r + 5 + 2r
4r + 2r + 5
6r + 5
