Answer:
141 and 582
Step-by-step explanation:
x,y,z are all single digit integers.
y = 4z - in order to be single digit, z must equal 0,1, or 2.
x = y-3 - since y is a single digit, the greatest x can be is 6 (when y is equal to 9). Assuming Y also has to be greater than three because x cannot be negative or equal to zero.
Based on this assumption, y cannot equal zero therefore z cannot equal zero.
If z=1, y=4, and x=1 making 141 a solution.
If z=2, y=8, and x=5 making 582 a solution.
