Linear Algebra
For which values of 'a' will the following system have no solutions? Exactly one solution? Infinitely many solutions? x + 2y - 3z = 4 3x - y +5z = 2 4x + y + (a^2-14)z = a+2

Linear Algebra
I got: x1 = -3*(x2) -2*(x5) + 66*(x6) - 22 x2 = free x3 = 33*(x6) - 11 x4 = -18*(x6) + 6 x5 = free x6 = free Is that correct?

Linear Algebra
Express the solutions of the following systems in terms of the free variables: x1 + 3*(x2) - 2*(x3) + 2*(x5) = 0 2*(x1) + 6*(x2) - 5*(x3) - 2*(x4) + 4*(x5) - 3*(x6) = -1 5*(x3) + 10*(x4) + 15*(x6) = 5 2*(x1) + 6*(x2) + 8*(x4) + 4*(x5) + 18*(x6) = 6
