<u>ANSWER </u>

<u>EXPLANATION</u>
We the have the equations,

Multiplying through by negative one gives,

Also

and

Dividing through by 2 gives

Making z the subject gives,

Now we substitute equation (3) into equation (1) and (2)
Equation (3) in to equation (1) gives,

This implies that;


We now put equation (3) in (2) to get,

This implies that



But

So,




Dividing through by negative 9 gives

and


Therefore
