To find the equivalent expression of -6n+(-12)+4n, we can start by combining like terms:
-6n + (-12) + 4n = (-6n + 4n) + (-12) = -2n + (-12) = -2n - 12
So, the equivalent expression of -6n+(-12)+4n is -2n - 12.
Therefore, the equivalent expression of -6n+(-12)+4n−6n+(−12)+4n is (-2n - 12) - (-2n - 12) = 0.
