Homework Help: Linear Transformations and Coordinate

1. The problem statement, all variables and given/known data

Let B be a basis of R^2 consisting of the vectors <5,2> and <1,5> and let R be the basis consisting of <2,3> and <1,2>

Find a matrix P such that [x]_r=P[x]_b for all x in R^2
2. Relevant equations

Ax=B?

3. The attempt at a solution


I attempted by using Ax=B as a format to solve for P, or x in the equation. I took the inverse of the column matrix of B because B is a basis, and if I am correct, a matrix's basis is defined as its coordinates ([x]_b).

I understand the geometrical interpretation of a linear transformation, yet I have no idea how to represent the transformation as a matrix. I would love an in depth description to approach similar exercises.
