    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
