If the system of equations
x + 2y + 3z = 3
4x + 3y – 4z = 4
8x + 4y – λz = 9 + μ
has infinitely many solutions, then the ordered pair (λ, μ) is equal to:
1
\(\left(-\frac{72}{5}, \frac{21}{5}\right)\)
2
\(\left(-\frac{72}{5},-\frac{21}{5}\right)\)
3
\(\left(\frac{72}{5},-\frac{21}{5}\right)\)
4
\(\left(\frac{72}{5}, \frac{21}{5}\right)\)
