Hey there!
Okay, so when you get a problem like this, all you need to do in insert the given value into the function and solve.
For example:
As you can see, they state that (a) = 27, so you insert 27 in for a in the function and it will look like this:
h(27) = 3(27) + 5
Now you solve on the right side of the equal sign:
3(27) = 81 (you multiply them)
81 + 5 = 86
When you plug the value of 27 in for a in this function, your output is equal to 86.
Answer: 22/3 or 7,(3)
Solution:
h(a)=3a+5
h(a)=27
3a+5=27
3a=27-5
3a=22
a=22/3
a=7,(3)
