Hi was wondering if anyone would be able to help me solve the following question; Find the value(s) of α for which the following system has no solution: x+y+z=1 2x + 3y =3 y + αz =4 the fourth variable has me confused.

Solve between the first 2 equations to eliminate the x which gives y-2z=1. When you solve this with y+az=4 you can see that a=-2 gives no solution.
