This one will be a little less finished...
Notice that we have a nice little 2 x 2 system that will give us the yand 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
Now, stick y = 2 and z = 6 into the first equation to pop x:
|So, the answer is||.|
* Notice that the 2 x 2 is x and y this time.
You'll pop z in the last step.
