Solution for Inx+In(x-5)=In(7x) equation:


Simplifying
Inx + In(x + -5) = In(7x)

Reorder the terms:
nxI + nI(-5 + x) = In(7x)
nxI + (-5 * nI + x * nI) = In(7x)
nxI + (-5nI + nxI) = In(7x)

Reorder the terms:
-5nI + nxI + nxI = In(7x)

Combine like terms: nxI + nxI = 2nxI
-5nI + 2nxI = In(7x)

Remove parenthesis around (7x)
-5nI + 2nxI = nI * 7x

Reorder the terms for easier multiplication:
-5nI + 2nxI = 7nI * x

Multiply nI * x
-5nI + 2nxI = 7nxI

Solving
-5nI + 2nxI = 7nxI

Solving for variable 'n'.

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

Add '-7nxI' to each side of the equation.
-5nI + 2nxI + -7nxI = 7nxI + -7nxI

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

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

Factor out the Greatest Common Factor (GCF), '-5nI'.
-5nI(1 + 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 '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing n to the left, all other terms to the right.
