Answer:
It's the first option! :)
Step-by-step explanation:
2x + 2k = m, right?
So, to bring 2k alone, we'll subtract 2x.
2k = m - 2x
Now, we'll divide both sides by 2! ^ _ ^
k = (m - 2x) / 2
That's pretty much just the (1)st option! :)
A
Try to get k by itself, just like you would do on a regular equation. Hopefully I help you get it right! Good luck!
