Step-by-step explanation:
We know that a day contains 24 hours in total.
The time already passed will be represented by
.
The remaining time would be
, becasye half of what has already passed remains until the end of the day.
Basically, the sum of these two expression gives 24 hours in total.
![x + \frac{x}{2} =24\\\frac{3x}{2}=24\\ x=16](https://tex.z-dn.net/?f=x%20%2B%20%5Cfrac%7Bx%7D%7B2%7D%20%3D24%5C%5C%5Cfrac%7B3x%7D%7B2%7D%3D24%5C%5C%20x%3D16)

Answer:
The answer to your question is Katie had 15 rocks and Oliver 45 rocks.
Step-by-step explanation:
Conditions
Katie has x amount of rocks
Oliver has 3x amount of rocks
The final amount of rocks
Oliver = 3x + 75
Katie = x + 105
Now, they have the same amount of rocks, then we can equal both equations
3x + 75 = x + 105
Solve for x
3x - x = 105 - 75
2x = 30
x = 30/2
x = 15
Conclusions
At first Katie had 15 rocks and Oliver had 3(15) = 45 rocks
(8x + 2y) - (7x + 2y) = 30 - 24
X = 6
