Answer:
x + 13
Valencia's height is 13 feet above the original height.
Explanation:
You are trying to solve how much Valencia is away from her original place.
Solve. Let Valencia's starting position be x. Valencia climbs 25 feet up the rock wall (Add 25):
x + 25
Valencia then climbs 12 feet down (Subtract 12):
x + 25 (-12)
Simplify. Combine like terms:
x + 25 - 12
x + (25 - 12)
x + 13
Valencia's height is 13 feet above the original height.
