Answer 2

Answer:

=> n = 6

Step-by-step explanation:

Given that:-

$2n + -1 = 11$

To find:- The value of the expression,

Reorder the terms:

=> $-1 + 2n = 11$

On solving it we get,

=> $-1 + 2n = 11$  

Solving for variable 'n'.  

Add '$1$' to each side of the equation.

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

Combine like terms: $-1 + 1 = 0$

=> $0 + 2n = 11 + 1$

=> $2n = 11 + 1$

Combine like terms: $11 + 1 = 12$

=> $2n = 12$  

Divide each side by '$2$'.

=> $n = 6$

Hence, the required solution is 6.
