that this is from a lot like the glass one. We just did. You can see that this equation is the same thing as this first equation just multiplied by two in this third equation is the same thing is the 1st 1 multiplied by four. So all these equations are essentially equivalent. Um, and therefore, any x, y and Z that satisfies one of these equations satisfies all these equations. Infinitely many solutions. Um, you could have 001 You could have 10 zero. You could have a negative one 11 any of the any three numbers where they added.
