The first thing i want to do to solve this equation is the three distributing parts.
00:13
So i will start by distributing here, here, and here.
00:18
Just be careful all three of them, i'm distributing a negative.
00:22
So be careful, especially with the second part of each distributing.
00:24
So i would wind up, that would be a minus four.
00:27
So then minus six plus 21p and then minus eight minus four p.
00:35
Next, because everything's on one side of my equation, of my equal sign, i want to combine all my like terms.
00:43
So negative 16, my coefficients plus 21 is 5, minus 4 would give me 1p, and now i'm going to combine all of my numbers that don't have variables.
00:55
Be careful, it's negative 4 minus 6 is negative 10.
00:59
Negative 10 minus 8 is negative 18, so that would be 1 p minus 18 equals 0.
01:05
Finally, i have to isolate my p, so i need to use the opposite operation here and add 18 to both sides...
