Answer:
Oh, hello there! Let's work on this equation together.
38.2 + -1 = 11
Let's create a table to keep track of our work.
-1 38.2 11
+1 37.2 12
As you can see, we added 1 to both sides to cancel out the negative 1.
So now, our equation is 37.2 = 12.
Let's subtract 12 from both sides.
-12 37.2 11
-12 25.2 -1
And there you have it! The solution is 25.2.
I hope this helps!
