The solution is

<u>EXPLANATION</u>
We have

and

Let us substitute equation (1) in to equation (2). This gives us,

We rewrite this as a quadratic equation as the highest degree is 2.

This implies that

we factor to obtain,



This means,


We substitute this values into any of the above equations, preferably equation (1)
