Sounds like rearranging to me:

P=2(a+b) -- expand brackets
P=2a+2b -- subtract 2a
P-2a=2b -- divide by 2

b=(P-2a)/2

$P=2(a+b)\\
P=2a+2b\\
2b=P-2a\\
b=\frac{P-2a}{2}$

Answer:

-6 +8d -2c

Step-by-step explanation:

$\frac{-2}{5} (15 -20d +5c) = \frac{-2}{5} \times 15 - \frac{-2}{5}\times20d +\frac{-2}{5}\times5c = -6 + 8d -2c$
