3(n-12)-n=3(n-12)

Solution for 3(n-12)-n=3(n-12) equation:

Simplifying
3(n + -12) + -1n = 3(n + -12)

Reorder the terms:
3(-12 + n) + -1n = 3(n + -12)
(-12 * 3 + n * 3) + -1n = 3(n + -12)
(-36 + 3n) + -1n = 3(n + -12)

Combine like terms: 3n + -1n = 2n
-36 + 2n = 3(n + -12)

Reorder the terms:
-36 + 2n = 3(-12 + n)
-36 + 2n = (-12 * 3 + n * 3)
-36 + 2n = (-36 + 3n)

Add '36' to each side of the equation.
-36 + 36 + 2n = -36 + 36 + 3n

Combine like terms: -36 + 36 = 0
0 + 2n = -36 + 36 + 3n
2n = -36 + 36 + 3n

Combine like terms: -36 + 36 = 0
2n = 0 + 3n
2n = 3n

Solving
2n = 3n

Solving for variable 'n'.

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

Add '-3n' to each side of the equation.
2n + -3n = 3n + -3n

Combine like terms: 2n + -3n = -1n
-1n = 3n + -3n

Combine like terms: 3n + -3n = 0
-1n = 0

Divide each side by '-1'.
n = 0

Simplifying
n = 0
