Given that,

An expression : [tex]\dfrac{e}{4}+2f-3[/tex]

To find,

The value of the above expression when e = 12 and f = 1/2

Solution,

We have,

[tex]\dfrac{e}{4}+2f-3[/tex]

Put e = 12 and f = 1/2

So,

[tex]=\dfrac{12}{4}+2\times \dfrac{1}{2}-3\\\\=3+1-3\\\\=1[/tex]

So, the value of the above expression is 1.
