Step 1
The
matrix
equation
can be written as a
set
of
equations
.
2
=
2
2
=
2
9
=
9
9
=
9
0
=
x
0
=
x
5
=
y
5
=
y
z
=
0
z
=
0
Step 2
Rewrite the
equation
as
x
=
0
x
=
0
.
x
=
0
x
=
0
5
=
y
5
=
y
z
=
0
z
=
0
Step 3
Rewrite the
equation
as
y
=
5
y
=
5
.
y
=
5
y
=
5
x
=
0
x
=
0
z
=
0
z
=
0
Step 4
List all of the
solutions
.
y
=
5
,
x
=
0
,
z
=
0
y
=
5
,
x
=
0
,
z
=
