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.
