If I had to guess that it mean -4x + 6y = -18 and y = -2x+21:

Since we have a y =, we can plug that in.

-4x + 6(-2x + 21) = -18

-4x -12x + 126 = -18

-16x = -18 -126

-16x = -144

-16x/-16 = -144/-16

x = 9

Answer:

$f( \frac{3}{ {x}^{2} - 16 } ) = ({\frac{3}{ {x}^{2} - 16 }})^{2} - 7(\frac{3}{ {x}^{2} - 16 }) + 12 \\ = \frac{9}{ {x}^{4} - 32 {x}^{2} + 256 } - \frac{21}{ {x}^{2} - 16} + 12$
