This one will be a
little less finished...
Notice that we have a nice little
2 x 2
system that will give us the
y
and z
answers... Then, we'll just stick those into the first
equation and we'll have
x!
Working the
2 x 2,
eliminate the z...
to get y...
Then, use the y
to pop
the z...
Now, stick
y =
2
and z
= 6
into the first equation to pop
x:
| So, the
answer is |
 |
. |
YOUR
TURN:
* Notice that the
2 x 2
is x and
y this time.
You'll pop z
in the last step.
