To determine which equation models the scoring in the final round and the contest outcome, we should rearrange each option to see if they represent a valid scoring situation based on comparable terms.

Let’s look at each equation:

A. 4x – 12 + 132 = 12x + 56

Rearranging gives us (4x + 120 = 12x + 56).

This simplifies to (120 – 56 = 12x – 4x), which is valid.

B. 12x + 4x – 132 = 12x + 56

Simplifying gives us (16x – 132 = 12x + 56).

Rearranging leads to (4x = 188) which is also valid.

C. 12x – 4x + 132 = 12x + 56

This simplifies to (8x + 132 = 12x + 56).

Rearranging gives (76 = 4x), which is valid.

D. 12x – 4x – 132 = 12x + 56

This simplifies to (8x – 132 = 12x + 56).

Rearranging gives (-132 – 56 = 4x), leading to a different validity.

Depending on the context of the problem, each equation
