Five times the difference of twice a number and seven is negative twenty-five.
Simplifying
Adding 35 on both sides
Dividing both sides by 10
Verification:
![5[2(1)-7] = -25\\5(2-7) = -25\\5(-5) = -25\\-25=-25](https://tex.z-dn.net/?f=5%5B2%281%29-7%5D%20%3D%20-25%5C%5C5%282-7%29%20%3D%20-25%5C%5C5%28-5%29%20%3D%20-25%5C%5C-25%3D-25)

The best way to solve this is by giving a visual idea of the glass ornaments. so We will have letter G represent Green, O for Orange, B for Brown, P for Purple.
Sample 1:G,O,B,P
Sample 2:G,P,O,B
Sample 3:P,G,O,B
Sample 4:O,G,P,B
Sample 5:G,O,P,B
This is what you can do this should be the right amount of ways to arrange them.
