the condition that must be satisfied is that x, y and z must all be multiples of 5.

first, we guess value of x (which must be a multiple of 5). And then we solve for corresponding value of y. Note that the value of y calculated must also be a multiply of 5. If it's not, guess another x value:

x: 5 , 10 , 15

y: 8 , 5 , 2

we see here that the only x and y value that satisfies the condition is

x = 10 and y = 5

now i think you forgot to type the choices.
