Answer:

k < - 11

Explanation:

- 3k - 12 > - k + 10 ( add k to both sides )

- 2k - 12 > 10 ( add 12 to both sides )

- 2k > 22

Divide both sides by - 2 , reversing the symbol as a result of dividing by a negative quantity.

k < - 11

Hi!

----------------------------------------------------------------------------------------------------------------

-3k-12>-k+10

-3k+k>10+12

-2k>22

-k>11

Now, when we divide by a negative variable, we change the sign of our inequality:

k<-11

Hope it helps!
