Given:
$e-\frac{1}{2}f$ (1)
$e=15,f=2$
substitute the values of e and f in equation (1)
we have
$15-\frac{1}{2}\left(2\right)$
$15-1$
14
Therefore $e-\frac{1}{2}f=14$

You enter the number for each letter into the equation when evaluating an expression.
$15-\frac{1}{2}\left(2\right)$ Now use order of operations to simplify
$15-1=14$
