Data:
\(x = - 3\) (I)
\(y = - 2x + 3\) (II)

Solving: Substitute (I) in (II)
\(y = - 2x + 3\)
\(y = - 2*(-3) + 3\)
\(y = 6 + 3\)
\(\boxed{y = 9}\)

With the first equation solved, all you need to do here is to plug the first equation into the second.
\(x=-3\\ y=-2x+3\\ \\ y=-2(-3)+3\\ y=+6+3\\ y=9\\ So\ y\ is\ equal\ to\ 9.\)
