Solution for n-2n=-3(4+3n)+6(n+7) equation:


Simplifying
n + -2n = -3(4 + 3n) + 6(n + 7)

Combine like terms: n + -2n = -1n
-1n = -3(4 + 3n) + 6(n + 7)
-1n = (4 * -3 + 3n * -3) + 6(n + 7)
-1n = (-12 + -9n) + 6(n + 7)

Reorder the terms:
-1n = -12 + -9n + 6(7 + n)
-1n = -12 + -9n + (7 * 6 + n * 6)
-1n = -12 + -9n + (42 + 6n)

Reorder the terms:
-1n = -12 + 42 + -9n + 6n

Combine like terms: -12 + 42 = 30
-1n = 30 + -9n + 6n

Combine like terms: -9n + 6n = -3n
-1n = 30 + -3n
