it's here given X plus Y plus the zero X plus y minus Z equals two and acts minus. Why plus see people's here. So here we have two equations that both equals zero. Which means we can set these equations equal to each other. Athlete Extra swipe Z equals X minus water plus z And what you notice years that these axes air gonna both cancel. And these ease air gonna both castle What? You're left with us. Why equals the negative? Why? This is only true if you move the why over you can actually solve it to Aiko zero. So why equals zero now we have that. Why equals zero? We can use this. Um, Now all we need are two of these equations, right? Because of, like, zero. That means that explosive E equals zero and X minus Z equals two. Let's solve or value system equations to equate to equations Two unknowns so we can solve using substitution. Actually closed Z plus two and then we plug this in Z plus two plus Z equals zero to Z equals negative too. This is gonna give us Z equals negative one z equals negative one. So Now we have a Y equals zero z equals negative one. We look at this first equation. This means that X gonna have to equal one. Now we have our order. Triple X Y Z equals one euro. Negative one with a double check. Makes it This works. We have the axe. 10 plus negative one equals zero. Now we have one plus y zero minus negative one that equals two one minus zero plus negative one that equals zero. So we have
