Simplifying
In(7x + 8) = In(2x + -22)

Reorder the terms:
nI(8 + 7x) = In(2x + -22)
(8 * nI + 7x * nI) = In(2x + -22)
(8nI + 7nxI) = In(2x + -22)

Reorder the terms:
8nI + 7nxI = nI(-22 + 2x)
8nI + 7nxI = (-22 * nI + 2x * nI)
8nI + 7nxI = (-22nI + 2nxI)

Solving
8nI + 7nxI = -22nI + 2nxI

Solving for variable 'n'.

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

Add '22nI' to each side of the equation.
8nI + 22nI + 7nxI = -22nI + 22nI + 2nxI

Combine like terms: 8nI + 22nI = 30nI
30nI + 7nxI = -22nI + 22nI + 2nxI

Combine like terms: -22nI + 22nI = 0
30nI + 7nxI = 0 + 2nxI
30nI + 7nxI = 2nxI

Add '-2nxI' to each side of the equation.
30nI + 7nxI + -2nxI = 2nxI + -2nxI

Combine like terms: 7nxI + -2nxI = 5nxI
30nI + 5nxI = 2nxI + -2nxI

Combine like terms: 2nxI + -2nxI = 0
30nI + 5nxI = 0

Factor out the Greatest Common Factor (GCF), '5nI'.
5nI(6 + x) = 0

Ignore the factor 5.

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 '(6 + x)' equal to zero and attempt to solve: Simplifying 6 + x = 0 Solving 6 + x = 0 Move all terms containing n to the left, all other terms to the right.
