10=2n+1

A. 4 1/2

B. 5 1/2

C. 4

A

Step-by-step explanation:

First you subtract the 1 from both sides of your equation.

10=2n+1 would turn into:

9=2n

Then divide both sides by 2 to get the n by itself

(9/2) = (n/2)

This will equal 4.5; which, equals 4 1/2

n = 4 1/2

Step-by-step explanation:

Given the equation

10 = 2n + 1

Subtract 1 from both sides of the equation

We have, 10-1 = 2n + 1-1

9 = 2n

Divide bothsides by 2 to get the unknown n

9/2 = 2n/2

4 1/2 = n

Therefore n = 4 1/2
