C(n)=-6+5(n-1)

Solution for C(n)=-6+5(n-1) equation:

Simplifying
C(n) = -6 + 5(n + -1)

Multiply C * n
nC = -6 + 5(n + -1)

Reorder the terms:
nC = -6 + 5(-1 + n)
nC = -6 + (-1 * 5 + n * 5)
nC = -6 + (-5 + 5n)

Combine like terms: -6 + -5 = -11
nC = -11 + 5n

Solving
nC = -11 + 5n

Solving for variable 'n'.

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

Add '-5n' to each side of the equation.
-5n + nC = -11 + 5n + -5n

Combine like terms: 5n + -5n = 0
-5n + nC = -11 + 0
-5n + nC = -11

Reorder the terms:
11 + -5n + nC = -11 + 11

Combine like terms: -11 + 11 = 0
11 + -5n + nC = 0
