An=-2(n-3)

Solution for An=-2(n-3) equation:

Simplifying
An = -2(n + -3)

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

Solving
nA = 6 + -2n

Solving for variable 'n'.

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

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

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

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

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