Okay, again, solving an equation for y with decimals.
00:10
So to make it a little bit easier for you with decimals, which is not nearly as important with fractions, you can move the decimals over as long as you do it to every single term.
00:18
So pretty much what you're doing.
00:20
In this case, i want to move two decimal places.
00:22
So that's multiplying times 100.
00:24
So you distribute 100 to both terms on the left, and then you distribute 100 to both terms on the right, so that way it would be fair.
00:33
And so all you can think of is that you just two places.
00:37
But the thing is, be careful.
00:38
You might want to just do one right here, but you have to do two.
00:41
I have to do two to each term.
00:43
I have to do two to each term.
00:45
If you're going to do it to one term, you have to do it to all terms.
00:47
So that's going to be 15y minus 10 equals 250y minus 104.
01:02
Okay.
01:02
And so like i said, it could make it easier.
01:04
It could not, not nearly as important as a fraction port.
01:08
All right.
01:08
And so then the next thing is to put like terms on the same side.
01:11
I'm going to add 10 to the right, or both sides, and it's going to cancel on the left.
01:15
And i'm going to subtract 250 y from the both sides, and it's going to cancel out on the right.
01:23
So now what i have is i have a negative 235 y equals 94, negative negative 94.
01:42
And so what i'm going to do? and x is i'm going to divide by negative 235...
