Answer:

Explanation:
Given system of equations:

Before we can compute xyz, we first need to find the values of x, y and z. To do this, we must solve the given system of equations.
Rearrange the second and third equations to isolate x and z, respectively:

Substitute these into the first equation and solve for y:

Now, substitute the found value of y into the two rearranged equations to find the values of x and z:

Now we have found the values of x, y and z, we can multiply them to compute xyz:

Therefore, the computation of xyz is:
