v3 pg 60 cap market deflation tend to undermine debt-financed assets

They mention 2 impacts of deflation. Can anyone explain if LTV is 67%, and if the value declines by 5% the equity will decline by 15%. Huh?

67 = Debt, 100 = Value, Equity = 33

Now value declines 5%

67=Debt, Value = 95, Equity = 28

28 / 33 = 84.8 % --> declined 15%

Super thanks CPK. obviously I need a break, as it sounds logical if you broke it down.

greetz from the dutchies.
