k=4

#### Work Step by Step

We need to get the k alone, so we cancel out the addition by subtracting 4 on both sides. This leaves us with the equation $-5k=-20$. We cancel out multiplication by using division, so we divide both sides of the equation by -5 to get that k=4. We plug 4 in for k and confirm that our answer is, indeed, correct.
