If we're solving for p for both of these, notice how they're set up in pretty much the exact same way.
00:08
The only difference is, is a here has numbers for everything other than p, and then b here has just variables.
00:17
So whatever steps we do here to solve this one, we can pretty much follow those same steps here to solve for p as well.
00:23
So let's see what we would need to do.
00:25
Now, we have 10p minus 3 on this side.
00:30
So all of our p are already grouped together.
00:32
So we just need to get everything else around from it on the other side.
00:37
So we have 10p minus 3.
00:39
So the 10p is one unit.
00:40
So we're asking ourselves, well, how do we get rid of this subtracting 3? well, the opposite of subtracting 3 is adding 3.
00:46
So we're going to add 3 to each side.
00:49
And we're going to end up with 10p is equal to 22.
00:56
Then on the other side, we have where we are multiplying by 10.
01:01
So we ask yourselves, well, what's the opposite of multiplying by 10? well, it's dividing by 10.
01:05
So we need to divide each side by 10.
01:08
And then we're going to get p is equal to 22 over 10, which, well, we can divide both of those by 2.
01:14
That would give 11 over 5...
