3n+2 (-2n-1) evaluate

-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
