$a= \frac{- 12 (C + A)}{C + A - 1}$

Step-by-step explanation:

Assuming we want to solve:

$C=\frac{a}{a+12}-A$

Add A to both sides;

$C + A=\frac{a}{a+12}$

Cross multiply;

(C + A)(a + 12) = a

Expand:

a(C + A) + 12 (C + A) = a

Group similar terms:

a(C + A) - a= - 12 (C + A)

Factor:

a((C + A) - 1)= - 12 (C + A)

$a= \frac{- 12 (C + A)}{C + A - 1}$
