Answer:
x2 = 60
Step-by-step explanation:
If the variables x and y are inversely proportional, the product x * y is a constant.
So using x1 and y1 we can find the value of this constant:
![x1 * y1 = k](https://tex.z-dn.net/?f=x1%20%2A%20y1%20%3D%20k)
![12 * 15 = k](https://tex.z-dn.net/?f=12%20%2A%2015%20%3D%20k)
![k = 180](https://tex.z-dn.net/?f=k%20%3D%20180)
Now, we can use the same constant to find x2:
![x2 * y2 = k](https://tex.z-dn.net/?f=x2%20%2A%20y2%20%3D%20k)
![x2 * 3 = 180](https://tex.z-dn.net/?f=x2%20%2A%203%20%3D%20180)
![x2 = 180 / 3 = 60](https://tex.z-dn.net/?f=x2%20%3D%20180%20%2F%203%20%3D%2060)
So the value of x2 is 60.
