The given equations can be solved simultaneously to find the values of x, y, and z.

From the first equation, 2xy = 16, we can divide both sides by 2 to get xy = 8.

From the second equation, x + z = 9, we can subtract z from both sides to get x = 9 - z.

From the third equation, 5z = 25, we can divide both sides by 5 to get z = 5.

Substituting the value of z into the second equation, we get x = 9 - 5 = 4.

Finally, substituting the values of x and z into the first equation, we get 2(4)y = 16, which simplifies to 8y = 16. Dividing both sides by 8, we get y = 2.

Therefore, the values of x, y, and z are 4, 2, and 5 respectively.
