F(n)=6+9(n-1)

Solution for F(n)=6+9(n-1) equation:

Simplifying
F(n) = 6 + 9(n + -1)

Multiply F * n
nF = 6 + 9(n + -1)

Reorder the terms:
nF = 6 + 9(-1 + n)
nF = 6 + (-1 * 9 + n * 9)
nF = 6 + (-9 + 9n)

Combine like terms: 6 + -9 = -3
nF = -3 + 9n

Solving
nF = -3 + 9n

Solving for variable 'n'.

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

Add '-9n' to each side of the equation.
-9n + nF = -3 + 9n + -9n

Combine like terms: 9n + -9n = 0
-9n + nF = -3 + 0
-9n + nF = -3

Reorder the terms:
3 + -9n + nF = -3 + 3

Combine like terms: -3 + 3 = 0
3 + -9n + nF = 0
