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? (1 point)

Answer 1

Let's represent the height Cheyenne's brother climbed as x.

According to the problem, Cheyenne climbs 129 feet more than her brother climbs, so we can represent her height climbed as x + 129.

Since she climbed a total of 468 feet, the equation can be written as:

x + 129 = 468
