The weight of the boat translates to a volume of water displaced. When this volume of displaced water is less than the volume of the hull, the boat will float.
(weight(boat) x density(water)) / Total volume of the hull = percentage of hull submerged, i.e waterline

Answer:
(x, y) = (20, 449)
Step-by-step explanation:
When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...
21.95x +10 = 22.45x
10 = 0.50x . . . . . subtract 21.95x
20 = x . . . . . . . . .multiply by 2
y = 22.45x = 22.45·20 = 449
