n=-3+(n-1)(-2.2)

Solution for n=-3+(n-1)(-2.2) equation:

Simplifying
n = -3 + (n + -1)(-2.2)

Reorder the terms:
n = -3 + (-1 + n)(-2.2)

Reorder the terms for easier multiplication:
n = -3 + -2.2(-1 + n)
n = -3 + (-1 * -2.2 + n * -2.2)
n = -3 + (2.2 + -2.2n)

Combine like terms: -3 + 2.2 = -0.8
n = -0.8 + -2.2n

Solving
n = -0.8 + -2.2n

Solving for variable 'n'.

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

Add '2.2n' to each side of the equation.
n + 2.2n = -0.8 + -2.2n + 2.2n

Combine like terms: n + 2.2n = 3.2n
3.2n = -0.8 + -2.2n + 2.2n

Combine like terms: -2.2n + 2.2n = 0.0
3.2n = -0.8 + 0.0
3.2n = -0.8

Divide each side by '3.2'.
n = -0.25

Simplifying
n = -0.25
