) a water tank is emptying steadily by 2 liters of water per hour. there were 2 liters of water 6 hours after midnight. let x re
present the number of hours since midnight, and let y represent the number of liters of water in the tank. find the equation showing the amount of water at time x.
First of all, let's find the water tank total amount according to the exercice, there were 2 L (L =liters) of water at 6 am (6hours after midnight ). Consider T as total amount of water so we have T=(6×2)+2=14 as we already know it's emptying 2 L per hour
