So here we have a system of equations with four equations.
00:05
That means that you have four rows in your matrix.
00:12
And then, of course, we have an x, a y, and a z in each of these, or almost all of them.
00:18
So that means that you need three columns, x, y, z, and then your constant column.
00:23
So you'll have your x column here, your y column here, your z column here, and your constant column.
00:31
So let's get started.
00:32
For our first equation, you have your coefficient for your x is 1.
00:37
Your coefficient for your y is negative 1...
