• A) \(x = - 3 , y = 1 , z = 2\)
• B) \(x = - 3 , y = 2 , z = 1\)
• C) \(x = 2 , y = 1 , z = - 3\)
• D) inconsistent (no solution)

Definitions:

Continuous Reinforcement

Reinforcing the desired response every time it occurs.

Partial Reinforcement

A conditioning schedule in which a reward is not administered every time the desired response is performed, leading to more resistant learned behavior.

Primary Reinforcement

A stimulus that satisfies basic survival needs and is inherently rewarding, such as food, water, or warmth, used in behavioral conditioning.

Negative Reinforcer

A stimulus whose removal or avoidance following a behavior increases the likelihood of that behavior occurring again in the future.
