37.2.6 Solving Linear Systems with Matrices
Core ideaWrite several equations as Ax = b, and if the determinant isn't zero there's a unique solution, found by elimination or the inverse matrix.
Module goal. Express direction and transformation with vectors and matrices, understand linear transformations, determinants, and solving systems of equations, and lay the groundwork for higher dimensions and abstract structures.
