Question:medium

If $ x = \alpha, y = \beta, z = \gamma $ is the solution of the system of equations $ 2x+3y+z=-1 $, $ 3x+y+z=4 $, $ x-3y-2z=1 $, then the value of $ \beta $ is

Show Hint

When solving a 3x3 system for only one variable, plan your eliminations. Pick a variable to eliminate first (like $ \gamma $ here) to reduce the system to 2x2, which is much easier to solve.
