3 (n+11) - 5n=-2 (n-12) + 9

Simplifying

3 (n + 11) + - 5n = - 2 (n + - 12) + 9

Reorder the terms:

3 (11 + n) + - 5n = - 2 (n + - 12) + 9

(11 * 3 + n * 3) + - 5n = - 2 (n + - 12) + 9

(33 + 3n) + - 5n = - 2 (n + - 12) + 9

Combine like terms: 3n + - 5n = - 2n

33 + - 2n = - 2 (n + - 12) + 9

Reorder the terms:

33 + - 2n = - 2 (-12 + n) + 9

33 + - 2n = (-12 * - 2 + n * - 2) + 9

33 + - 2n = (24 + - 2n) + 9

Reorder the terms:

33 + - 2n = 24 + 9 + - 2n

Combine like terms: 24 + 9 = 33

33 + - 2n = 33 + - 2n

Add '-33' to each side of the equation.

33 + - 33 + - 2n = 33 + - 33 + - 2nCombine like terms: 33 + - 33 = 0

0 + - 2n = 33 + - 33 + - 2n

-2n = 33 + - 33 + - 2n

Combine like terms: 33 + - 33 = 0

-2n = 0 + - 2n

-2n = - 2n

Add '2n' to each side of the equation.

-2n + 2n = - 2n + 2n

Combine like terms: - 2n + 2n = 0

0 = - 2n + 2n

Combine like terms: - 2n + 2n = 0

0 = 0
