# Linsys find --- Introduction ---

Linsys find is an exercise that asks you to establish a linear system according to texts of various styles, in particular systems having infinitely many solutions.

Note that you can also use the exercise Equaffine for establishing systems defining affine subspaces (line, plane, hyperplane, etc).
