    n = 2

    Step-by-step explanation:

    Simplifying

    13n + - 9 = 17

    Reorder the terms:

    -9 + 13n = 17

    Solving

    -9 + 13n = 17

    Solving for variable 'n'.

    Move all terms containing n to the left, all other terms to the right.

    Add '9' to each side of the equation.

    -9 + 9 + 13n = 17 + 9

    Combine like terms: - 9 + 9 = 0

    0 + 13n = 17 + 9

    13n = 17 + 9

    Combine like terms: 17 + 9 = 26

    13n = 26

    Divide each side by '13'.

    n = 2

    Simplifying

    n = 2
