Let $P$ be the point $(2,5)$ in $(x,y)$ coordinates. Find the coordinates of $P$ in the $(x^\prime,y^\prime)$ coordinate system, in which the coordinate axes have been translated 8 units to the right of the $(x,y)$ coordinates.

Let $Q$ be the point $(10,3)$ in $(x^\prime,y^\prime)$ coordinates. Find the coordinates of $Q$ in the $(x,y)$ coordinate system, in which the $(x,y)$ coordinate axes have been translated 7 units to the left of the $(x^\prime,y^\prime)$ coordinates.
