F(n)=3+4(n-1)

Solution for F(n)=3+4(n-1) equation:

Simplifying
F(n) = 3 + 4(n + -1)

Multiply F * n
nF = 3 + 4(n + -1)

Reorder the terms:
nF = 3 + 4(-1 + n)
nF = 3 + (-1 * 4 + n * 4)
nF = 3 + (-4 + 4n)

Combine like terms: 3 + -4 = -1
nF = -1 + 4n

Solving
nF = -1 + 4n

Solving for variable 'n'.

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

Add '-4n' to each side of the equation.
-4n + nF = -1 + 4n + -4n

Combine like terms: 4n + -4n = 0
-4n + nF = -1 + 0
-4n + nF = -1

Reorder the terms:
1 + -4n + nF = -1 + 1

Combine like terms: -1 + 1 = 0
1 + -4n + nF = 0
