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

Solution for 3(n+2)=3(n-1) equation:

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

Reorder the terms:
3(2 + n) = 3(n + -1)
(2 * 3 + n * 3) = 3(n + -1)
(6 + 3n) = 3(n + -1)

Reorder the terms:
6 + 3n = 3(-1 + n)
6 + 3n = (-1 * 3 + n * 3)
6 + 3n = (-3 + 3n)

Add '-3n' to each side of the equation.
6 + 3n + -3n = -3 + 3n + -3n

Combine like terms: 3n + -3n = 0
6 + 0 = -3 + 3n + -3n
6 = -3 + 3n + -3n

Combine like terms: 3n + -3n = 0
6 = -3 + 0
6 = -3
