Hello,
I need to solve the following equation. It's important to follow the Gaussian method. There's also a sample calculation attached. The problem is that I've never worked with an equation where two equations have 0 in front of the x, and I don't know how to proceed.
Thank you in advance!

I want to create my own math library in Python and am currently working on sine. I'm using the unit circle as a guide. I'm creating a right-angled triangle within it. By entering a second angle, I can determine the third angle. I also know the length of the hypotenuse (c=1). How can I calculate…
Hello, I'm currently trying to solve a math problem involving ratios, but my previous approach always seems to be wrong. I would be very grateful if someone could help me by showing me the correct solution. Thank you in advance for your support. Best regards, """" the task is: When shifted, point A is mapped…
Also erstmal steht da nicht 0 vor dem x sondern 1 und es macht es in der Regel leichter, wenn Koeffizienten übereinstimmen. Du kannst hier direkt die 3. gleichung von der 1. Abziehen und wenn du die 3. Mal 2 nimmst dann auch von der 2. Gleichung.
Übrig bleibt dann:
2x = 6
-x + 8y = -3
x – 2y + 2z = 1
Von da an ist es selbsterklärend.
Dankeschön
