    I'll show you how to work this kind of problem.

    n+23.4=36.9

    You want to get the knowns on one side and the unknown on the other side.

    Subtract 23 from both sides.

    n = 36.9 - 23.4
    n = 13.5

    I'll be glad to check your work on the first problem.

    Note: you'll need to add 45 to both sides.
