Answer

d=1/2

Work Step by Step

We first use the distributive property to simplify the equation to $-4.8=-9.6d$. We cancel out multiplication by using division, so we divide both sides of the equation by -9.6 to get that d=1/2. We plug 1/2 in for d and confirm that our answer is, indeed, correct.
