All real numbers. the domain is all numbers grater than zero
The price of the boat in 6 years will be

(12,75%=0.1275 - the <span>reduction factor of boat value;</span> after each year the price will decrease in 0.8725 times and after six years will decrease in

times)
Here, Equations are: x - y = 6
y = x - 4
x - y = 4
Here, we can see L.H.S of both equations are equal but R.H.S is unequal so the system has no solution at all.
In short, Your Answer would be "No Solution"
Hope this helps!
