Solve - 2 (n+3) - 4=8. The solution is n=.

n = - 9

Step-by-step explanation:

Simplifying

-2 (n + 3) + - 4 = 8

Reorder the terms:

-2 (3 + n) + - 4 = 8

(3 * - 2 + n * - 2) + - 4 = 8

(-6 + - 2n) + - 4 = 8

Reorder the terms:

-6 + - 4 + - 2n = 8

Combine like terms: - 6 + - 4 = - 10

-10 + - 2n = 8

Solving

-10 + - 2n = 8

Solving for variable 'n'.

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

Add '10' to each side of the equation.

-10 + 10 + - 2n = 8 + 10

Combine like terms: - 10 + 10 = 0

0 + - 2n = 8 + 10

-2n = 8 + 10

Combine like terms: 8 + 10 = 18

-2n = 18

Divide each side by '-2'.

n = - 9

Simplifying

n = - 9
