Determinants and Cramer's Rule Practice
This is a listing of the "crunch some" problems for this chapter
Determinants - 2x2's

Example:  | ( -4, 7 ) ( 5, -2 ) |

Determinants - 3x3's

Example:  | ( -4, 7, -1 ) ( 5, -2, 3 ) ( -6, 0, 8 ) |

Cramer's Rule for solving 2x2 systems

Example:  Solve  2x-5y=22  and  3x+7y=-25

Cramer's Rule for solving 3x3 systems

Example:  Solve  x-3y+5z=-14  and  2x+y-6z=20  and  3x-2y+z=0
