What is - 4 is greater than or equal to k minus 2

-4 >or = k-2

Make sure to have k alone on one side of the inequality.

Add + 2 to each side since you want k alone and by removing - 2 you have to take the opposite of the sign which is addition.

-2> or = K

K could be less than - 2 or it could be exactly - 2.
