Find the values of $x$ and $y$ . A triangle divided into two triangles by a segment from one vertex to the opposite side. The triangle on the right has a single arc in each angle. One side of this triangle is labeled 5 y minus 4. The common side of the two triangles is labeled 3 x minus 5. In the second triangle, two angles have a double arc. One of these angles is opposite the common side of the two triangles. The other is opposite a side labeled y + 12. $x=$ $y=$
