Answer:8 and 12
Step-by-step explanation: 8 is 4 less than 12 and 12 and 8 equals 20
10.

Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13
Hope this helped, I tried to explain it easily.
