Answer
$$(2,-1,-1).$$
Work Step by Step
The parametric equations of the line are given by
$$ x=2+t, \quad y=-1+2t, \quad z=-1-4t.$$
Now, substituting in the equation of the plane
$$2x+y =3\Longrightarrow 4+2t-1+2t=3\\
\Longrightarrow 4t=0\Longrightarrow t=0.
$$
So the point of intersection is given by $$(2,-1,-1).$$
