Write a problem you can represent with 2k-10=6

Add the 10 on both sides so you have 2k=16 then divide both by 2 so k=8

I thinks you mean to solve for "k". To do this you must isolate the k on one side of the equation. Use the distribution method:

2k-10 = 6

Add 10 to both sides of equation

2k = 16

Divide both sides by 2

k = 8

To check the answer, substitute it in to the original equation:

2 (8) - 10 = 6

16-10 = 6

6 = 6

So the answer is correct.
