Answer:
=4
Step-by-step explanation:
For the first one:
![t \: - \: 2e = 20](https://tex.z-dn.net/?f=t%20%5C%3A%20%20-%20%20%5C%3A%202e%20%3D%2020)
you change the subtract 2 to add 2 on both sides. so it looks like the picture above. Then you would add 20 + 2 to equal 22. Then you divide that by 1 (from the t). that equals 22, so thats the answer.
If you use the Fundamental Counting Principle, you can figure out the answer.
