Please Answer!

Answer 1

K/6+8=5                           C/2+5=1
K/6=-3                              C/2=-4
K=-18                               C=-8

9+A/6=8                          D/4-9=-3
A/6=-1                             D/4=6
A=-6                                D=24

Answer 2

$\frac{k}{6}+ 8 = 5$⇔$\frac{k}{6} = 5-8$⇔$\frac{k}{6} = -3$⇔$k = -3*6$⇔$k = -18$
K = -18
The others are just doing the same thing:
C = -2
A = -6
D = 24
