Question

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!!
