Solving for variable 'n'.

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

Add '8nI' to each side of the equation.
-5nI + 8nI + 2nxI = -8nI + 8nI + nxI

Combine like terms: -5nI + 8nI = 3nI
3nI + 2nxI = -8nI + 8nI + nxI

Combine like terms: -8nI + 8nI = 0
3nI + 2nxI = 0 + nxI
3nI + 2nxI = nxI

Add '-1nxI' to each side of the equation.
3nI + 2nxI + -1nxI = nxI + -1nxI

Combine like terms: 2nxI + -1nxI = 1nxI
3nI + 1nxI = nxI + -1nxI

Combine like terms: nxI + -1nxI = 0
3nI + 1nxI = 0
