    -n-2

    Step-by-step explanation:

    First do 2 (-2n) and 2 (-1)

    You get - 4n-2

    Then add 3n to the equation

    3n-4n-2

    Combine Like Terms

    3n-4n=-n

    Final Answer:

    -n-2

    The answer is N = - 2 Simplifying

    3n + 2 (-2n + - 1) = 0

    Reorder the terms:

    3n + 2 (-1 + - 2n) = 0

    3n + (-1 * 2 + - 2n * 2) = 0

    3n + (-2 + - 4n) = 0

    Reorder the terms:

    -2 + 3n + - 4n = 0

    Combine like terms: 3n + - 4n = - 1n

    -2 + - 1n = 0

    Solving

    -2 + - 1n = 0

    Solving for variable 'n'.

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

    Add '2' to each side of the equation.

    -2 + 2 + - 1n = 0 + 2

    Combine like terms: - 2 + 2 = 0

    0 + - 1n = 0 + 2

    -1n = 0 + 2

    Combine like terms: 0 + 2 = 2

    -1n = 2

    Divide each side by '-1'.

    n = - 2

    Simplifying

    n = - 2
