Mai poured `2.6` liters of water into a partially-filled pitcher. The pitcher now contains `10.4` liters. Mai wants to know how
many liters of water were originally in the pitcher. Three of Mai’s friends drew a diagram (shown) to represent the problem. You said the solution to your equation `2.6+10.4=` was `13`.
Explain what the solution to the equation means within the context of the problem.
Step-by-step explanation: If we want to find the amount that was in the pitcher before then we subtract 2.6 from 10.4 to find the original amount because if the pitcher were to contain an amount that only adds up to 10.4 before we add 2.6 then the number that adds with 2.6 to equal 10.4 is our answer
