00:00:00.840 --> 00:00:03.189 A:middle L:90%
we're being asked to solve the given equation. So
2
00:00:03.189 --> 00:00:05.400 A:middle L:90%
we have Negative. 23 is equal to nine minus
3
00:00:05.400 --> 00:00:07.580 A:middle L:90%
for X. So remember, the first thing we
4
00:00:07.580 --> 00:00:09.960 A:middle L:90%
don't need to do in order to isolate are variable
5
00:00:10.160 --> 00:00:12.869 A:middle L:90%
is moved the term that's not attached to our X
6
00:00:12.880 --> 00:00:14.490 A:middle L:90%
. So in other words, we wanna move that
7
00:00:14.490 --> 00:00:17.780 A:middle L:90%
positive nine over to the left hand side. Well
8
00:00:17.780 --> 00:00:19.670 A:middle L:90%
, what's the opposite of adding nine to negative four
9
00:00:19.670 --> 00:00:21.550 A:middle L:90%
X? Well, that would be to subtract nine
10
00:00:21.559 --> 00:00:23.710 A:middle L:90%
. So we're gonna go ahead and subtract nine from
11
00:00:23.710 --> 00:00:26.129 A:middle L:90%
both sides of our equation on. We know this
12
00:00:26.129 --> 00:00:28.250 A:middle L:90%
is the right thing to do because nine minus nine
13
00:00:28.250 --> 00:00:30.469 A:middle L:90%
is zero. So these first terms will cancel out
14
00:00:31.440 --> 00:00:33.070 A:middle L:90%
. So on the left hand side, we have
15
00:00:33.070 --> 00:00:36.149 A:middle L:90%
negative 23 minus nine, which is negative 32.
16
00:00:36.640 --> 00:00:38.439 A:middle L:90%
And on the right hand side, we just have
17
00:00:38.439 --> 00:00:40.859 A:middle L:90%
negative four X. So now we just have a
18
00:00:40.859 --> 00:00:43.719 A:middle L:90%
one step equation. Well, X is gonna multiplied
19
00:00:43.719 --> 00:00:46.329 A:middle L:90%
by negative four. So the opposite is to divide
20
00:00:46.329 --> 00:00:49.880 A:middle L:90%
both sides of our equation by negative four again.
21
00:00:49.890 --> 00:00:52.090 A:middle L:90%
The reason why, because negative four, divided by
22
00:00:52.090 --> 00:00:54.310 A:middle L:90%
negative four is equal a positive one. So these
23
00:00:54.310 --> 00:00:57.500 A:middle L:90%
terms cancel so on the left hand side, we
24
00:00:57.500 --> 00:01:00.320 A:middle L:90%
have negative 32 divided by negative four. Well,
25
00:01:00.320 --> 00:01:02.990 A:middle L:90%
that's going to be positively and on the right hand
26
00:01:02.990 --> 00:01:04.349 A:middle L:90%
side, which was left with X. So now
27
00:01:04.349 --> 00:01:07.519 A:middle L:90%
we've solved our equation. So have found that eight
28
00:01:07.530 --> 00:01:08.480 A:middle L:90%
is equal to X, and it's perfectly fine to
29
00:01:08.480 --> 00:01:11.049 A:middle L:90%
leave your answer like this. Or you can flip
30
00:01:11.049 --> 00:01:14.349 A:middle L:90%
this around and say that X is equal to positive
31
00:01:14.349 --> 00:01:15.650 A:middle L:90%
. Eight. Either way is perfectly fine.
