Evaluate means substitute...

so when x=4 then: $\frac{x+6}{x-3}=\frac{4+6}{4-3}=\frac{10}{1}=\boxed{10}$

now you try when x=18

Looks good!

You probably want to leave that as 8/5, depending on what your teacher wants.

Two different questions were asked, therefore you have two different answers.

Tell me, if I said evaluate 2-1 and then evaluate 5-3 do you think you would add the different answers together?

Edit: well I see you figured it out yourself
