<em>This question will be answered using trial by error method and the solution is not limited to one equation.</em>
<em></em>
One equation that matches the values above is:.
To check:
Substitute the values of x, y and z in the above equation.
Hence,
Because both sides of the equation are one and the same (-4), is true for the above values of x, y and z.
