Step-by-step explanation:
Let Oliver's be x
Let Stephanie's be y
![x = 2y - - - (a) \\ x + y = 96 - - - (b)](https://tex.z-dn.net/?f=x%20%3D%202y%20-%20%20-%20%20-%20%28a%29%20%5C%5C%20x%20%2B%20y%20%3D%2096%20-%20%20-%20%20-%20%28b%29)
substitute for x in (b):
![2y + y = 96 \\ 3y = 96 \\ y = 32](https://tex.z-dn.net/?f=2y%20%2B%20y%20%3D%2096%20%5C%5C%203y%20%3D%2096%20%5C%5C%20y%20%3D%2032)
find x in (a):
![x = (2 \times 32) \\ x = 64](https://tex.z-dn.net/?f=x%20%3D%20%282%20%5Ctimes%2032%29%20%5C%5C%20x%20%3D%2064)
