$k=-11/2$
We need to get the k alone. Thus, we cancel out the addition by subtracting 3 on both sides. This leaves us with the equation $-2k=11$. In order to cancel out multiplication, we use division, so we divide both sides by -2 to get that $k=-11/2$. We plug -11/2 in for k and confirm that our answer is, indeed, correct.
