Answer»

Make both equal to 15 xy, and therefore equal to each other.

20x + 30y = 24x + 27y

3y = 4x

you can then substitute this in the first equation

4x+8x = x (4x) make this into a quadratic

4x squared - 12x = 0, the only real integer is 3 (the other is zero).

x = 3, and y must therefore be 4.
