Answer: School Y has 4 points and School X has 12 points.
Step-by-step explanation:
Let the number of points School Y has be x
Let the number of points School X has be 3x
According to question, we get
![3x-x=8\\\\2x=8\\\\x=(8)/(2)\\\\x=4](https://img.qammunity.org/2019/formulas/mathematics/high-school/vp9t5nm6zy2qj6509xj24qwutz8xzmr2sn.png)
So, the number of point School Y has 4.
and number of points School X has
![3x=3* 4=12](https://img.qammunity.org/2019/formulas/mathematics/high-school/dsyelntgyon5nkrjuewg5u2v91nt6guxm6.png)
Hence, School Y has 4 points and School X has 12 points.
