Now here we look at a few statements, right, and see whether true falls.
00:08
The first says a homogeneous linear system equation always has at least one solution.
00:13
This is of course false, right? a matrix in r -r -e -f form must contain only zeros and ones.
00:23
This is also false.
00:26
It's also false.
00:29
Every matrix can be reduced to a metric, r -r -e -f metrics.
00:34
No, non -mancery, this is also.
00:37
False.
00:39
If an linear system equations in actual form, every variable is either leading or free, but not both.
00:46
And this is actually correct.
00:50
So this is the correct thing.
00:51
Two by three metrics may be multiplied by two by three.
00:54
This is false, right? a two by three measure maybe added two or two.
00:58
Yeah, that's true...
