Ifn+6-2n=2(n+3)

Solution for Ifn+6-2n=2(n+3) equation:

Simplifying
Ifn + 6 + -2n = 2(n + 3)

Reorder the terms:
6 + fnI + -2n = 2(n + 3)

Reorder the terms:
6 + fnI + -2n = 2(3 + n)
6 + fnI + -2n = (3 * 2 + n * 2)
6 + fnI + -2n = (6 + 2n)

Add '-6' to each side of the equation.
6 + fnI + -6 + -2n = 6 + -6 + 2n

Reorder the terms:
6 + -6 + fnI + -2n = 6 + -6 + 2n

Combine like terms: 6 + -6 = 0
0 + fnI + -2n = 6 + -6 + 2n
fnI + -2n = 6 + -6 + 2n

Combine like terms: 6 + -6 = 0
fnI + -2n = 0 + 2n
fnI + -2n = 2n

Solving
fnI + -2n = 2n

Solving for variable 'f'.

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

Add '2n' to each side of the equation.
fnI + -2n + 2n = 2n + 2n

Combine like terms: -2n + 2n = 0
fnI + 0 = 2n + 2n
fnI = 2n + 2n

Combine like terms: 2n + 2n = 4n
fnI = 4n

Divide each side by 'nI'.
f = 4I-1

Simplifying
f = 4I-1
