-3nI + 2nxI = 7nI

Solving
-3nI + 2nxI = 7nI

Solving for variable 'n'.

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

Add '-7nI' to each side of the equation.
-3nI + -7nI + 2nxI = 7nI + -7nI

Combine like terms: -3nI + -7nI = -10nI
-10nI + 2nxI = 7nI + -7nI

Combine like terms: 7nI + -7nI = 0
-10nI + 2nxI = 0

Factor out the Greatest Common Factor (GCF), '2nI'.
2nI(-5 + x) = 0

Ignore the factor 2.

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

Set the factor '(-5 + x)' equal to zero and attempt to solve: Simplifying -5 + x = 0 Solving -5 + x = 0 Move all terms containing n to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x = 0 + 5 x = 0 + 5 Combine like terms: 0 + 5 = 5 x = 5 Add '-1x' to each side of the equation. x + -1x = 5 + -1x Combine like terms: x + -1x = 0 0 = 5 + -1x Simplifying 0 = 5 + -1x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
