9nI + 12nxI = (8nI + 2nxI)

Solving
9nI + 12nxI = 8nI + 2nxI

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.
9nI + -8nI + 12nxI = 8nI + -8nI + 2nxI

Combine like terms: 9nI + -8nI = 1nI
1nI + 12nxI = 8nI + -8nI + 2nxI

Combine like terms: 8nI + -8nI = 0
1nI + 12nxI = 0 + 2nxI
1nI + 12nxI = 2nxI

Add '-2nxI' to each side of the equation.
1nI + 12nxI + -2nxI = 2nxI + -2nxI

Combine like terms: 12nxI + -2nxI = 10nxI
1nI + 10nxI = 2nxI + -2nxI

Combine like terms: 2nxI + -2nxI = 0
1nI + 10nxI = 0

Factor out the Greatest Common Factor (GCF), 'nI'.
nI(1 + 10x) = 0

Subproblem 1

Set the factor 'nI' equal to zero and attempt to solve: Simplifying nI = 0 Solving nI = 0 Move all terms containing n to the left, all other terms to the right. Simplifying nI = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2
