Unformatted text preview: ose A and B are n × n matrices. If AB is invertible, then A
and B are both invertible. Outline Number of Solutions Solving Multiple Systems More Results On the Inverse Example Example
What conditions on b1 , b2 , b3 will make the following system of
linear equations consistent:
x1 − 2x2 + 5x3 = b1
4x1 − 5x2 + 8x3 = b2
−3x1 + 3x2 − 3x3 = b3...
