This problem is telling you to find two ways to solve HE+ME=WE when all letters are a number between 0 and 9. So H, E, M, W are all numbers.
For example, let's say H is 1.
So you got 1E+ME=WE
Then, let's say E is 3.
So you get 3+3M=3W
If M was let's say... 2?
You'd get 3+6=3W, which means that 3W equals 9.
Divide both sides by 3 and you get W=3. Now, you know that H is 1, E is 3, M is 2 and W is 3.
The problem is asking you to find two solutions and i just gave you one. Good luck!
