is this correct?

6k-9=15
k=4

I just want to know if i did it right

yes you are correct

You didn't show your work so I don't know if you did it right or not. Your answer is correct.

i did 9=15 which equal 24 and i divided that by 6 which =4 so k must equal 4..........did i do it right?

i mean 15+9 im sorry

Right!
Of course you can check your answer by substuting your answer for the unknown.

(6 x 4) - 9 = 15

Thank you!!

You're welcome! Just to clarify, when solving the equation 6k - 9 = 15, you added 9 to both sides to isolate the variable, resulting in 6k = 24. Then, you divided both sides by 6 to solve for k, giving you k = 4. Finally, you substituted your answer into the original equation (6 x 4) - 9 = 15 to confirm that it satisfies the equation. Well done! If you have any more questions, feel free to ask.
