x +y = 20 ( rewrite as x = 20-y)
3x - 3y =30
3(20-y) - 3y = 30
60-3y - 3y = 30
60-6y = 30
-6y = -30
y = -30 / -6 = 5
x=20-5 = 15
x = 15, y = 5
The level has dropped 11 mms in 22 hours
that is 0.5mm per hour
So the remaining 31 mm will be gone in 31 / 0.5 = 62 hours
62 hours after 11 am Wednesday brings us to 11 am Friday + 14 hours
= 1 am Saturday. answer
