Answer:

y=1, x=-4

Step-by-step explanation:

Solve by substitution. [tex](-16y=4x) = ( y=\frac{4x}{-16} )=(y=-\frac{x}{4} )[/tex]

[tex](4x +27y=11)=[4x+27(-\frac{x}{4} )=11][/tex]

Simplified[tex]\begin{bmatrix}-\frac{11x}{4}=11\end{bmatrix}[/tex]

Solved[tex]x=-4[/tex]

Substitute again[tex]-16y=4(-4)[/tex]

[tex]-16y=-16[/tex]

Solve[tex]y=1[/tex]
