Alright you've bothered me long enough.
You've bugged me about helping you with solving systems of equations using matrices for too long.
I've solved using a matrix yesterday so I'll use that as an example.
So here's the equation.
3x + 4y + 9z = 4
5x - 2z + 8y = 3
2y + 3z + 5x = -1
You press 2nd then x -1. These are both on the left side.
2nd

math
x-1
Once inside of the matrix menu press the right arrow twice then press EDIT.
Press enter once your curser is hovering over
1: [ A ]. Place 3 x 4 as the perimeters of the matrix.
MATRIX [ A ] 3 x 4
Then place the equation into the matrix, excluding the x's. y's, and z's.
[ 3 4 9 4 ]
[ 5 -2 8 3 ]
[ 2 3 5 -1 ]
Once finished, go back to the matrix menu and go right one and select MATH.
Scroll down to B: rref( and select it.
Then go back to the menu and select
1: [ A ] 3x4, then press enter.
[ 1 0 0 -5 ]
[ 0 1 0 -2 ]
[ 0 0 1 3 ]
x = -5
y = -2
z = 3
So there. That's how you solve a system of equations using a matrix.
I hope you remember all of that cause that is the last time I'll explain it to you.
Buh-bye. See you in class.
