Answer:
(x, y) = (40, 2)
Explanation:
Taking the antilog of the second equation, we have ...
x/y^2 = 10
x = 10y^2
Substituting this into the first equation gives ...
(10y^2)y = 80
y^3 = 8 . . . . . . . . divide by 10
y = 2 . . . . . . . . . . cube root
x = 10·2^2 = 40
The solution is (x, y) = (40, 2).
