Question

which method you would use to solve the following system of equations and why you chose that method?
x – 2y + z = 0
2x – 3y – 4z = –9
x + 2y – 5z = 0

Answer 1

I would use the elimination method. First, the first and last equation, you can get rid of the y variable.

Answer 2

You then add them and use that equation to solve the third. So I would recommend that you use the substitution method.

Answer 3

@zordoloom So which one? Elimination or Substitution?

Answer 4

I would use elimination.
