1nI + 5nxI = nI(7 + 3x)
1nI + 5nxI = (7 * nI + 3x * nI)
1nI + 5nxI = (7nI + 3nxI)

Solving
1nI + 5nxI = 7nI + 3nxI

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.
1nI + -7nI + 5nxI = 7nI + -7nI + 3nxI

Combine like terms: 1nI + -7nI = -6nI
-6nI + 5nxI = 7nI + -7nI + 3nxI

Combine like terms: 7nI + -7nI = 0
-6nI + 5nxI = 0 + 3nxI
-6nI + 5nxI = 3nxI

Add '-3nxI' to each side of the equation.
-6nI + 5nxI + -3nxI = 3nxI + -3nxI

Combine like terms: 5nxI + -3nxI = 2nxI
-6nI + 2nxI = 3nxI + -3nxI

Combine like terms: 3nxI + -3nxI = 0
-6nI + 2nxI = 0

Factor out the Greatest Common Factor (GCF), '2nI'.
2nI(-3 + 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 '(-3 + x)' equal to zero and attempt to solve: Simplifying -3 + x = 0 Solving -3 + x = 0 Move all terms containing n to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + x = 0 + 3 x = 0 + 3 Combine like terms: 0 + 3 = 3 x = 3 Add '-1x' to each side of the equation. x + -1x = 3 + -1x Combine like terms: x + -1x = 0 0 = 3 + -1x Simplifying 0 = 3 + -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.
