I think you are suppose to get "k" by itself, so you first multiply 2/5 to (k - 2)
-8 ≤ 2/5 (k - 2)
-8 ≤ 2/5k - 4/5
Next you add 4/5 on both sides
-8 + 4/5 ≤ 2/5k
Then you make the denominators the same in order to add them
-40/5 + 4/5 ≤ 2/5k
-36/5 ≤ 2/5k
Finally you multiply each side by 5/2 to get "k" by itself
-18 ≤ k
