An equation would be y=-1x-1!
I hope this helped! Brainliest? :) -Raven❤️
The number of bottles in a full box is 12.
<u><em>Explanation</em></u>
Suppose, the number of bottles in a full box is 
So, the number of bottles in <u>three</u> full boxes 
Now, two more boxes are added, both of which have <u>one fewer bottle than the other three</u>. So, the number of bottles in these two boxes 
As there were 9 bottles initially and now there are 67 bottles in the fridge, <em><u>so the equation will be</u></em>....

Thus, the number of bottles in a full box is 12.
I have attached an image explaining how to solve this problem.
(“m” means slope)
2+3(2x-5)-3(4z+6)-8
2+3(2x)+3(-5)-3(4z)-3(6)-8
2+6x-15-12z-18-8
2-15+6x-12z-18-8
-13+6x-12z-26
-13-26+6x-12z
-39+6x-12z
6x-12z-39
3 < 37
I hope this helps you!
