Find the value of the expression below given that n = 20

Question

(3+n) -11

Answer 1

To find the value of the expression \((3 + n) - 11\) when \(n = 20\), substitute \(n\) with 20 in the expression.

Starting with the expression:
\[
(3 + n) - 11
\]

Substitute \(n\) with 20:
\[
(3 + 20) - 11
\]

First, perform the addition inside the parentheses:
\[
23 - 11
\]

Next, perform the subtraction:
\[
23 - 11 = 12
\]

Therefore, the value of the expression \((3 + n) - 11\) when \(n = 20\) is:
\[
12
\]
