Question

What are x,y, and z if x+y+4z=5, -2x+2z, 3x+y+2z=-1, i am desperate

Answer 1

Answer:

how I learned it in school was that the variable had to always equal something, so you would have to put on the side or where ever x=(a number) and also you multiply those numbers cause no sign would mean multiply (I'm so sorry if it's not write though, I hope I could help you a little)
