PUZZLE #4597: Matrix Eigenvector (diff 3)

eigenvector learn difficulty: 3/7 compute author: system unsolved

A 2x2 matrix and an eigenvalue are given. Compute the eigenvector to decode the password.

DATA

Matrix	`[-117, 97], [120, -94]`
Eigenvalue	`3`
Format	`Find eigenvector v such that M * v = lambda * v. The ASCII values of v's components decode to the password.`
Hint	`Compute the eigenvector for eigenvalue 3 of the given 2x2 matrix. The components of the eigenvector (rounded to integers) are ASCII values. Decode them.`
Answer Format	`comma-separated integers or floats`
