1. solve this system using matrices:
3.7x2.3+4.2z=8
2.6+4.6y3.9z=10
8x+2z=20
2. Write this system as a matrix equation:
2x+y=8
7x3y=10

#2
the square matrix
2 1
7 3
multiplied by the column matrix
x
y
=
8
10
(I can't think of another way to print matrices on this board)
1. I can't make out your equations.
