1. x−468=129

2. x+468=129

3. x+129=468

4. x−129=468

Answer 1

The correct equation that represents the problem is: x + 129 = 468.

Explanation:
Let x be the height that Cheyenne's brother climbed up the mountain.

The problem tells us that Cheyenne climbed 129 feet more than her brother, so her climb up the mountain can be expressed as (x + 129).

We also know that the total height climbed by both of them combined is 468 feet, so we can set up the equation:

x + (x + 129) = 468

Simplifying this equation gives:

2x + 129 = 468

Subtracting 129 from both sides gives us:

2x = 339

Dividing both sides by 2 gives:

x = 169.5

Therefore, Cheyenne's brother climbed 169.5 feet up the mountain.

So, the correct answer is: x + 129 = 468.
