$$
c = -4 - 7a - 3b
$$

This expression allows arbitrary real values for $ a $ and $ b $, generating infinitely many solutions.

2. Use Substitution or Elimination

If combined with another equation (e.g., $ a + b + c = k $), use substitution or elimination methods to solve the system completely.

3. Explore Parametric Solutions

Let $ a = t $, $ b = s $ (free parameters), then $ c = -4 - 7t - 3s $. This parametric form reveals a geometric plane in 3D space.
