Looks like the system is

We can eliminate
by taking




so that
, and



Substitute
into this last equation and solve for
:




Then



Plug these values into any one of the original equation to solve for
:




Hence the solution is x = 4, y = -3, and z = 2.
The correct option will be: A. 67%
<em><u>Explanation</u></em>
