-6n-2n=16

-6n and -2n have the same variable, so you can combine them.
-8n = 16

Divide both sides by -8 to isolate the variable.
n = -2

The answer is n = -2

Solve for n:
-6 n - 2 n = 16

-6 n - 2 n = -8 n:
-8 n = 16

Divide both sides of -8 n = 16 by -8:
(-8 n)/(-8) = 16/(-8)

(-8)/(-8) = 1:
n = 16/(-8)

The gcd of 16 and -8 is 8, so 16/(-8) = (8×2)/(8 (-1)) = 8/8×2/(-1) = 2/(-1):
n = 2/(-1)

Multiply numerator and denominator of 2/(-1) by -1:
Answer: n = -2
