\left\{ \begin{array} { l } { 2 x + 3 y = 4 z } \\ { 5 z + 2 = 1 } \\ { 4 y + k = 3 } \\ { 6 x y + z = 1 } \end{array} \right.
Solve for x, y, z, k
x=-\frac{\sqrt{26}i}{10}-\frac{1}{5}\approx -0.2-0.509901951i\text{, }y=\frac{-2+\sqrt{26}i}{15}\approx -0.133333333+0.339934634i\text{, }z=-\frac{1}{5}=-0.2\text{, }k=\frac{-4\sqrt{26}i+53}{15}\approx 3.533333333-1.359738537i
