How do you solve 81+2k=5k

subtract 2k from both sides so you have

81=3k

then divide both sides by 3 so you get

27=k

:D

Subract 2k from both sides. This gives you:
81=3k
Then divide both sides by 3. This gives you:
27=k
Hope this helps!

Im pretty sure you subtract 2k from 5k and you will get negative 3k and divide by 81 and you will get negative 27=K. Hope this helps.

basic.......
subtrack 2k from each side, to make it 81=3k
divide by 3 to find k.... whatever 81 divided by 3 is is k

Like this:
81+2k=5k
-2k. -2k
81=3k
3k. 3k
27=k
Hope this helps!(:
