    1. subtract 10N from both sides

    2. subtract 800 from both sides

    3. divide what's left by the coefficient of N

    Subtract 10N from both sides:

    800 + 12N - 10N = 1000 +10N-10N

    800 +2N = 1000

    subtract 800 from both sides

    800+2N-800=1000-800

    2N = 200

    Divide both sides by 2

    2N/2 = 200/2

    N = 100.
