Question

Find the value of the following expressions if n=3
i) 7n-3

Answer 1

Answer:

The value of the expression will be 18.

Step-by-step explanation:

In context to questions asked,

We have to find the value of $7n-3$,

Given that,

$7n-3$ where the value of n is 3.

Now, plug the value of n as 3 in the given expression:

=> 7n - 3

=> 7 ( 3 ) - 3

=> 21 - 3

=> 18

Hence, the required solution is 18.
