Problem: A tank initially had an amount of water (let's call it 'g'). But then, 3 gallons of water were removed from it and the remaining amount of water was 40 gallons. How much water was initially in the tank?

Claude-3 Opus:

Let's solve this step by step:

1. Let's define our variables:
   - Let 'g' be the initial amount of water in the tank.

2. We know that 3 gallons were removed from the tank, and the remaining amount was 40 gallons. We can represent this as an equation:
   - Initial amount - 3 gallons = 40 gallons
   - In terms of our variable: g - 3 = 40

3. To find the initial amount, we need to solve the equation for 'g':
   - Add 3 to both sides of the equation:
     g - 3 + 3 = 40 + 3
     g = 43

Therefore, the initial amount of water in the tank was 43 gallons.
