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