In this problem, we are going to solve for w.
00:04
It's a one -step equation.
00:06
And we're going to do that by multiplying by 5 on both sides.
00:09
We do that because this is called the multiplication property of equality.
00:13
When you multiply one side by a number, you have to multiply the other side by that number as well, so the equation remains true.
00:20
So let's see we have w divided by 5.
00:23
And to undo the divided by 5, we do the opposite operation.
00:26
We call this the inverse operation.
00:28
So we multiply by five.
00:31
Now when we multiply by five, what we're really doing is kind of canceling out the division of five...
