12x + 3(-4x-1) = 8 | <em>The bottom equation is replacing the y on the top equation</em>

<em />

Then solve it!

12x - 12x - 3 = 8

C lies on AB

True

BA is a ray on plane P

A ray passes through the plane. In this case, the line is on the plane, not passing through. So it is not a ray.

AB + BC = AC

True.

X, Y and Z are colinear

Colinear points are part of the same line. In this question, there is no line passing through these points, so they are not colinear.

W, A and Y are coplanar:

Coplanar points are on the same plane. In this item, points A and Y are on the same plane. However, point W is not, so they are not coplanar.
