Step-by-step explanation:
The food and drink( orginally carbon compunds) we take in are broken down into carbon compounds and most simplest being glucose (C6H12O6). When this glucose reacts with oxygen it forms carbon dioxide and water. So, this where CO2 comes from in the body. Energy is also released in the reaction which why we feel energetic after having food. This process is called cellular oxidation.

<span>y = x – 10...(1)
2x + y = 4....(2)
subsct in (2) : 2x+x-10=4
3x =14
x=14/3
y = 14/3-10 =-16/3
