Checking Solutions   In Exercises 9–12, determine whether each ordered triple is a solution of the system of equations.

\(\left\{\begin{aligned} 4 x+y-z &=0 \\ -8 x-6 y+z &=-\frac{7}{4} \\ 3 x-y &=-\frac{9}{4} \end{aligned}\right. \)

(a) (0, 1, 1)

(b) \(\left(-\frac{3}{2}, \frac{5}{4},-\frac{5}{4}\right)\)

(c) \(\left(-\frac{1}{2}, \frac{3}{4},-\frac{5}{4}\right)\)

(d) \(\left(-\frac{1}{2}, \frac{1}{6},-\frac{3}{4}\right)\)
