Is the equation conditional, an identity, or a contradiction? $$3 ( z + 2 ) - 2 z = - 2 \left( - \frac { 1 } { 2 } z + 1 \right) + 8$$
A) Conditional
B) Contradiction
C) Identity

The equation simplifies to $3z + 6 - 2z = z + 2 + 8$, which further simplifies to $z + 6 = z + 10$. Subtracting $z$ from both sides gives $6 = 10$, which is false, indicating a contradiction.
