To solve the equation \( c - a = d + r \) for \( a \), follow these steps:

1. Start with the given equation:
   \[
   c - a = d + r
   \]
   
2. Subtract \( c \) from both sides to isolate the term involving \( a \):
   \[
   -a = d + r - c
   \]

3. Multiply both sides by \( -1 \) to solve for \( a \):
   \[
   a = c - d - r
   \]

Thus, the solution for \( a \) is:
\[
a = c - d - r
\]
