Question

2n + 1 = 11 the value of n is ______

Answer 1

Answer:

$2n + 1 = 11 \\ \\ = 2n = 11 - 1 \\ \\ = 2n = 10 \\ \\ n = \frac{10}{2} \\ \\ = n = 5$

Answer 2

Answer:

=> n = 5

Step-by-step explanation:

Given that:-

$2n + 1 = 11$

To find:- The value of the $n$ for the expression,

In order to solve that, we have to use the concept of BODMAS:

It is the sequence of various mathematical operations which is used to solve the various expressions.

As we have,

=> $2n + 1 = 11$

Now, subtract both sides by $1$:

=> $2n + 1 -1= 11-1$

=> $2n=10$

Divide both sides by $2$, we get

=> n = 5

Hence, the required solution is 5.
