Respuesta :

first, subtract 1 from both sides of the equation.

You are left with 2n=20

Then, divide 2 into 20, and you get 10

So, the value of n is 10

Hope this helped!

The value of n obtained from equation 2n+1=21 is 10.

Value of n to be determined in equation 2n+1=21.

What is arithmetic?

Statements execute as mathematical expressions. In arithmetic mathematics deals with various statements, progressions, sequences etc.

Here,
      ⇒2n+1=21
          2n=21-1
          2n=20
           n=20/2
           n=10

Thus, the value of n in equation 2n+1=21 is 10.
