It's open, not because it has a variable, but because there is limited number of values (in this case one value only) of the variable that will make it true.

Answer 22

It's 8

Answer 23

Plug in your numbers

Answer 24

2*8-5=?
It's 11 in this case. :D

Answer 25

Indeed @mathstudent55 :D

Answer 26

Plug in each number for x. Then evaluate the left side. Whichever choice makes the left side equal to 11 is the answer

Answer 27

4y = -24
6
-6
96
-96

Answer 28

Once again, try each choice on the left side:
What is
4 * 6
4 * (-6)
4 * 96
4 * (-96)
The one that equals -24 is the answer.
