This is a very easy question. All required information's are already
present in the question. It only needs step by step procedure to
ultimately find the value of n. Now let us look into the given equation.
-8n + 4(1 + 5n) = -6n -14
-8n + 4 + 20n = -6n - 14
12n + 4 = -6n -14
12n + 6n = -14 - 4
18n = -18
n = - 18/18
= -1
So the value of n in the given equation is -1.
