00:00:00.930 --> 00:00:02.310 A:middle L:90%
here on this problem. We want to determine if
2
00:00:02.319 --> 00:00:05.089 A:middle L:90%
May give 31 is a solution to this system of
3
00:00:05.089 --> 00:00:07.429 A:middle L:90%
equations. Now, if it is, what that
4
00:00:07.429 --> 00:00:09.410 A:middle L:90%
means is that I complied. Negative three and four
5
00:00:09.410 --> 00:00:12.060 A:middle L:90%
X, but one. And for why? And
6
00:00:12.060 --> 00:00:14.250 A:middle L:90%
it gives me a true statement in both equations.
7
00:00:15.550 --> 00:00:17.429 A:middle L:90%
So looking here in this bottom equation, let me
8
00:00:17.429 --> 00:00:21.629 A:middle L:90%
put negative three in forex. Good one. And
9
00:00:21.629 --> 00:00:24.420 A:middle L:90%
for why? And let's see if that gives us
10
00:00:24.420 --> 00:00:31.129 A:middle L:90%
four. We have negative six plus 10. Is
11
00:00:31.129 --> 00:00:34.119 A:middle L:90%
that equal for? Well, yes, it does
12
00:00:34.130 --> 00:00:38.170 A:middle L:90%
. So it works in that bottom equation. Check
13
00:00:38.170 --> 00:00:40.159 A:middle L:90%
the top equation and then top equation. Port negative
14
00:00:40.159 --> 00:00:44.979 A:middle L:90%
three in forex would one in for wife is negative
15
00:00:44.979 --> 00:00:48.170 A:middle L:90%
. Three minus one equal negative for Yes, it
16
00:00:48.170 --> 00:00:51.869 A:middle L:90%
does. It tells us yes. This is a
17
00:00:51.869 --> 00:00:53.649 A:middle L:90%
solution to our system of equations.
