Finding The Constants a,b and c.

mardi 30 juillet 2013

1. The problem statement, all variables and given/known data

In Exercises 49 and 50, find values of a, b, and c(if possible) such that the system of linear equations has (a) a unique solution, (b) no solution, and (c) an infinite number of solutions.



49.



[itex]x+y ~ = 2[/itex]



[itex]~y+z =2[/itex]



[itex]x+ ~ z =2[/itex]



[itex]ax + by + cz=0[/itex]





2. Relevant equations







3. The attempt at a solution



I immediately recognized this system as one consisting of planes. Hence, wouldn't it be impossible for there to exist a unique solution, as my geometric intuition of the situation ?
