00:00:01.340 --> 00:00:05.049 A:middle L:90%
all right. Another galaxy and elimination problem. Um
2
00:00:05.740 --> 00:00:09.929 A:middle L:90%
, so I'm gonna live through these and figure out
3
00:00:10.160 --> 00:00:13.650 A:middle L:90%
what variable toe make the same and all the equations
4
00:00:14.140 --> 00:00:16.750 A:middle L:90%
. Um, I think I'm going with the wise
5
00:00:17.140 --> 00:00:24.850 A:middle L:90%
Simon and multiply this equation. Times three, huh
6
00:00:26.739 --> 00:00:30.870 A:middle L:90%
? To make it be six. Why wth this
7
00:00:30.940 --> 00:00:36.729 A:middle L:90%
equation by negative three to may this be six.
8
00:00:36.729 --> 00:00:42.750 A:middle L:90%
Why the situation? I think one and so that
9
00:00:42.759 --> 00:00:46.409 A:middle L:90%
made that b six. Why? Also? So
10
00:00:46.409 --> 00:00:49.250 A:middle L:90%
the result of doing that would be, um,
11
00:00:49.840 --> 00:00:56.250 A:middle L:90%
30 x three, x plus six. Why?
12
00:00:58.340 --> 00:01:07.450 A:middle L:90%
Minus 42 z equals 24. Then times negative three
13
00:01:08.180 --> 00:01:12.849 A:middle L:90%
means I get through yet. Plus, it's why
14
00:01:15.840 --> 00:01:26.599 A:middle L:90%
, um and then plus 12 equals three. Then
15
00:01:26.599 --> 00:01:30.950 A:middle L:90%
then finally, 12 x plus. It's why,
16
00:01:32.439 --> 00:01:42.700 A:middle L:90%
um Meyer, 60 meatballs, right? So then
17
00:01:44.739 --> 00:01:49.180 A:middle L:90%
I must attract these two equations. Distracted. I'm
18
00:01:49.180 --> 00:01:55.989 A:middle L:90%
gonna subtract also trying down here. Okay, So
19
00:01:56.000 --> 00:02:01.253 A:middle L:90%
30 minus three is 27. It's and then negative
20
00:02:01.263 --> 00:02:06.343 A:middle L:90%
42 minus 12. It's negative, or Z,
21
00:02:09.233 --> 00:02:13.242 A:middle L:90%
and that equals 24 months. Three is 21.
22
00:02:15.332 --> 00:02:17.473 A:middle L:90%
Then the same thing with these I must attract these
23
00:02:17.483 --> 00:02:21.643 A:middle L:90%
. I'll subtract them up. Bottom minus the top
24
00:02:22.133 --> 00:02:29.062 A:middle L:90%
. So 12 minus three is nine next and then
25
00:02:29.372 --> 00:02:31.492 A:middle L:90%
six months. 60 Negative. Six months. 12
26
00:02:31.502 --> 00:02:40.953 A:middle L:90%
on a team. See Equals, um 12 minus
27
00:02:40.953 --> 00:02:49.233 A:middle L:90%
three. It's not. Yeah. And then,
28
00:02:49.473 --> 00:02:53.513 A:middle L:90%
uh, multiply the bottom equation by free will make
29
00:02:53.522 --> 00:02:58.052 A:middle L:90%
the exes be the same. Right? So I
30
00:02:58.052 --> 00:03:07.043 A:middle L:90%
get 27. Yes, minus 54 Z equals 27
31
00:03:07.133 --> 00:03:09.062 A:middle L:90%
. And then again, I could subtract these two
32
00:03:09.062 --> 00:03:16.543 A:middle L:90%
equations and I get zero equals six as false.
33
00:03:17.633 --> 00:03:20.393 A:middle L:90%
So what we have here is a case. So
34
00:03:20.393 --> 00:03:25.453 A:middle L:90%
you have parallel planes. The beads will have no
35
00:03:25.453 --> 00:03:31.242 A:middle L:90%
solution. You comment? Yeah. So there's no
36
00:03:31.733 --> 00:03:32.742 A:middle L:90%
unique solution.
