Question Evaluate the expressions $c-9$ for $c=11$, $b+16$ for $b=4$, and $a-4$ for $a=y$.

Studdy Solution
Substitute $a = y$ into the expression.
$$y - 4$$
Since we are not given a specific value for $y$, the expression simplifies to $y - 4$.
The solutions are:
7. For $c = 11$, $c - 9 = 2$.
8. For $b = 4$, $b + 16 = 20$.
9. For $a = y$, $a - 4 = y - 4$.
