00:00:00.000 --> 00:00:01.000
Show me.
2
00:00:01.000 --> 00:00:02.000
Alright.
3
00:00:02.000 --> 00:00:07.000
What I like to do is show you guys how to solve this two-step equation.
4
00:00:07.000 --> 00:00:10.000
Now we're just learning how to do two-step equations.
5
00:00:10.000 --> 00:00:15.000
So there's a couple things we need to keep on remembering about these two-step equations.
6
00:00:15.000 --> 00:00:18.000
First thing is we want to kind of do the reverse order of operations.
7
00:00:18.000 --> 00:00:22.000
Remember order of operations start with the old Pendox, parentheses, exponents,
8
00:00:22.000 --> 00:00:25.000
multiply divide, and then add subtract.
9
00:00:25.000 --> 00:00:29.000
So when we're doing reverse order of operations, we want to start looking at adding subtractive first.
10
00:00:29.000 --> 00:00:33.000
So we want to look at undoing addition and subtraction first.
11
00:00:33.000 --> 00:00:38.000
So to undo them, we're going to have to use our inverse operations.
12
00:00:38.000 --> 00:00:39.000
Sorry?
13
00:00:39.000 --> 00:00:40.000
You're not going to do it.
14
00:00:40.000 --> 00:00:43.000
So our first thing we're going to do is our inverse operations.
15
00:00:43.000 --> 00:00:46.000
So we a lot of times you guys remember I circled the variable.
16
00:00:46.000 --> 00:00:48.000
For this problem, we're going to circle the variable x.
17
00:00:48.000 --> 00:00:50.000
I'll circle the variable.
18
00:00:50.000 --> 00:00:54.000
What that is telling us is we're just not going to do anything to this variable.
19
00:00:54.000 --> 00:00:55.000
This variable is pinned.
20
00:00:55.000 --> 00:00:57.000
We're not going to touch it.
21
00:00:57.000 --> 00:01:01.000
So now what you see, all right, let's undo what's undo addition is tracking.
22
00:01:01.000 --> 00:01:03.000
Is there anything that may add or subtract to the variable?
23
00:01:03.000 --> 00:01:05.000
You say yes, it's being added by four.
24
00:01:05.000 --> 00:01:09.000
So in an undo addition, we have to use the inverse operation with the subtract.
25
00:01:09.000 --> 00:01:15.000
Now you need to make sure you subtract on both sides because that's the property of the quality of subtraction.
26
00:01:15.000 --> 00:01:18.000
Wherever you don't want to side, you have to do on the other side, the other side.
27
00:01:18.000 --> 00:01:21.000
Therefore, four minus four gives you zero.
28
00:01:21.000 --> 00:01:24.000
We don't need to write three x plus zero.
29
00:01:24.000 --> 00:01:30.000
All right, then the next thing we need to look at is to say, all right, now what is happening to my variable?
30
00:01:30.000 --> 00:01:32.000
Well, my variable now is being multiplied.
31
00:01:32.000 --> 00:01:35.000
So the undo multiplication, the inverse operation would be.
32
00:01:35.000 --> 00:01:37.000
Yeah, that's right.
33
00:01:37.000 --> 00:01:41.000
Okay, so three divided by three is one.
34
00:01:41.000 --> 00:01:44.000
One times x is going to be x.
35
00:01:44.000 --> 00:01:48.000
Therefore, we look at this and we say just three going to eight.
36
00:01:48.000 --> 00:01:51.000
No, so we're just going to leave this as an improper fraction.
37
00:01:51.000 --> 00:01:54.000
All right, and that's how you solve the two-step equation.
38
00:01:54.000 --> 00:01:59.000
Just remember to always undo addition and subtraction first by inverse operations,
39
00:01:59.000 --> 00:02:03.000
then undo multiplication and division by inverse operations.
40
00:02:03.000 --> 00:02:06.000
Okay, yeah, lie.
41
00:02:06.000 --> 00:02:21.000
Okay, split.
