Answer
$(-3,-15)$
Work Step by Step
Variable $y$ is isolated in eq.$2$
$y=3x-6\qquad $(*)
Replace $y$ with $3x-6$ in the other equation:
$ 9x-2(3x-6)=3\qquad$ ... and solve for $x$. Simplify
$9x-6x+12=3$
$ 3x+12=3\qquad$ ... subtract $12$
$ 3x=-9\qquad$ ... divide with $3$
$x=-3$
Now, back-substitute into (*)
$y=3(-3)-6=-9-6=-15$
Form an ordered pair $(x,y) $ as the solution to the system
$(-3,-15)$
