00:00:00.000 --> 00:00:02.000
Alright.
2
00:00:02.000 --> 00:00:04.000
Thank you.
3
00:00:04.000 --> 00:00:06.000
Thank you.
4
00:00:06.000 --> 00:00:12.000
So from, on this problem we need to solve for W. So this is a one step equation.
5
00:00:12.000 --> 00:00:16.000
And when you're solving for this equation.
6
00:00:16.000 --> 00:00:21.000
So when it's solved for this equation, there's a couple things I notice.
7
00:00:21.000 --> 00:00:25.000
Here I have a fraction and then here I have a mixed number.
8
00:00:25.000 --> 00:00:29.000
So what I'm going to want to do is I'm going to want to change first of all my mixed number into an improper fraction.
9
00:00:29.000 --> 00:00:33.000
And for those of you that need a little review for that.
10
00:00:33.000 --> 00:00:39.000
The way that we want we like to do it is take your denominator,
11
00:00:39.000 --> 00:00:43.000
multiply it by your whole number and add it to your numerator.
12
00:00:43.000 --> 00:00:47.000
So two times one is two plus one is three.
13
00:00:47.000 --> 00:00:51.000
So as an improper fraction we can write this as three halves.
14
00:00:51.000 --> 00:00:54.000
So the next thing I'm going to do is I'm just going to rewrite my equation.
15
00:00:54.000 --> 00:00:58.000
So it's two thirds plus W equals three halves.
16
00:00:58.000 --> 00:01:02.000
Now I'm going to use my step for solving one step equation.
17
00:01:02.000 --> 00:01:07.000
And my step for solving one step equation is first I need to determine what is happening to my variable.
18
00:01:07.000 --> 00:01:10.000
My variable is my W in this case.
19
00:01:10.000 --> 00:01:12.000
So I need to determine what's happening to my variable.
20
00:01:12.000 --> 00:01:16.000
And I've been noticed I have an addition sign so I'm using an addition.
21
00:01:16.000 --> 00:01:19.000
So I'm actually adding to my variable two thirds.
22
00:01:19.000 --> 00:01:24.000
So the opposite of that is now I'm going to actually have to subtract.
23
00:01:24.000 --> 00:01:28.000
So you're going to want to you always determine first what happened to the variable.
24
00:01:28.000 --> 00:01:30.000
Then you need to determine what is the inverse operation.
25
00:01:30.000 --> 00:01:33.000
Well the inverse operation of addition would be subtraction.
26
00:01:33.000 --> 00:01:39.000
So I'm going to subtract two thirds from both sides of the equal sign.
27
00:01:39.000 --> 00:01:42.000
Any number subtracted by itself is going to remain zero.
28
00:01:42.000 --> 00:01:44.000
We don't need to write zero anymore.
29
00:01:44.000 --> 00:01:51.000
So we have W equals three halves minus two thirds.
30
00:01:51.000 --> 00:01:55.000
It's like real close to getting it like zero.
31
00:01:55.000 --> 00:01:58.000
Right when you take the video.
32
00:01:58.000 --> 00:02:01.000
Yes, it is zero.
33
00:02:01.000 --> 00:02:03.000
This becomes zero.
34
00:02:03.000 --> 00:02:07.000
But now we have three halves minus two thirds.
35
00:02:07.000 --> 00:02:11.000
So what we have to do is remember whenever we're adding or subtracting,
36
00:02:11.000 --> 00:02:13.000
we have to make sure that's the common denominator.
37
00:02:13.000 --> 00:02:18.000
So if I look what's the common denominator between two and two and three, it's going to be six.
38
00:02:18.000 --> 00:02:24.000
And therefore I have to multiply two times three from the top of the bottom.
39
00:02:24.000 --> 00:02:28.000
And two thirds and three times two on the top of the bottom.
40
00:02:28.000 --> 00:02:32.000
And the reason why I do this is because two times three is getting me six.
41
00:02:32.000 --> 00:02:35.000
And three times two will give me six.
42
00:02:35.000 --> 00:02:39.000
Three times three is nine. Two times two is four.
43
00:02:39.000 --> 00:02:43.000
And therefore I have W equals nine six minus four six.
44
00:02:43.000 --> 00:02:45.000
They have to become the nominers.
45
00:02:45.000 --> 00:02:47.000
So now I can subtract the numerators.
46
00:02:47.000 --> 00:02:51.000
So therefore my final answer becomes five six.
47
00:02:51.000 --> 00:02:52.000
Right?
48
00:02:52.000 --> 00:03:19.000
Okay.
