0x+2 =y
So technically x+2=y
        
             
        
        
        
Volume of the tank = length x width x height
Volume = 15.4 x 10 x 3 =  450 in³
Volume of one gallon = 231 in³
Then we need 450/231 gallons to fill the tank, that is 450/231 = 1.95 gallons

I hope this is what you're looking for. The concept of regrouping<span> (borrowing) is so that students can see what actually happens in it. For example, to </span>subtract <span>52 − 38, we write 52 as 50 + 2 (breaking it down into its tens and ones). Then, </span>regrouping<span> means that 50 + 2 becomes 40 + 12.</span>
