## Midterm Review Notes

Linear Systems A linear system is a set of linear equations. A linear system is consistent if it has 1 or infinite solutions, and inconsistent if it has no solutions. There are only 3 different situations to the solutions of a linear system: no solution (inconsistent) 1 solution (consistent) infinite solutions (consistent) A consistent linear system is different from a homogeneous one. Consistent means having solutions; Homogeneous means a linear system where all the constants are zero....
