Answer:

#k> -9#

Explanation:

To solve you need to get the k by itself.
To do this we can start by subtracting 12 from both sides.

#-2k+12-12<30-12#
#-2k<18#

Now we need to divide by -2. BUT as this is an inequality the inequality sign needs to be flipped when you divide both sides by a negative number.

#(-2k)/(-2)>18/(-2)#
#k> -9#
