What equation represents the following real-world problem? Cheyenne climbs 468 feet up a mountain. This is 129 feet more than her brother climbs. How high did Cheyenne’s brother climb up the mountain

could you help me

Let's call the height that Cheyenne's brother climbs "x" feet.

According to the problem, Cheyenne climbs 129 feet more than her brother, so her height climbed would be x + 129 feet.
Given that Cheyenne climbs 468 feet up the mountain, we can set up the equation:

x + 129 = 468

To find the height that Cheyenne's brother climbed, we can solve this equation for x:

x = 468 - 129
x = 339

Therefore, Cheyenne's brother climbed 339 feet up the mountain.
