Answer:
1: 9
2: 7
3: 5
4: 3
5: 1
Step-by-step explanation:
You have to substitute the x in y=-2x+11 for the numbers under the x column.
For example, for 1, you would do y=-2(1)+11, which would equal y=-2+11, which equals 9. You would do this for all of the x values.
Hope this helps!
Unfortunately your teacher is using x as both a variable and a multiplication sign. This is something that can be avoided by using something like the asterisk symbol to indicate multiplication.
Anyways, notice how the expression 
shows up twice. Once in the numerator (the entire numerator) and once again in the denominator (nearly the whole thing)
Let's replace that messy expression with the variable y. So we're letting 
This means,
At this point you can probably see how to get 
from here. The y terms cancel out when we divide leaving 1 up top and 3^x down below.

Step-by-step explanation:
x=black
y= blue
x+y=39
11+x=y
11+2x=39
28=x
