Solution for In(x+4)+In(x)=In(x+40) equation:


Simplifying
In(x + 4) + In(x) = In(x + 40)

Reorder the terms:
nI(4 + x) + In(x) = In(x + 40)
(4 * nI + x * nI) + In(x) = In(x + 40)
(4nI + nxI) + In(x) = In(x + 40)

Multiply nI * x
4nI + nxI + nxI = In(x + 40)

Combine like terms: nxI + nxI = 2nxI
4nI + 2nxI = In(x + 40)

Reorder the terms:
4nI + 2nxI = nI(40 + x)
4nI + 2nxI = (40 * nI + x * nI)
4nI + 2nxI = (40nI + nxI)

Solving
4nI + 2nxI = 40nI + nxI

Solving for variable 'n'.

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

Add '-40nI' to each side of the equation.
4nI + -40nI + 2nxI = 40nI + -40nI + nxI

Combine like terms: 4nI + -40nI = -36nI
-36nI + 2nxI = 40nI + -40nI + nxI

Combine like terms: 40nI + -40nI = 0
-36nI + 2nxI = 0 + nxI
-36nI + 2nxI = nxI

Add '-1nxI' to each side of the equation.
-36nI + 2nxI + -1nxI = nxI + -1nxI

Combine like terms: 2nxI + -1nxI = 1nxI
-36nI + 1nxI = nxI + -1nxI

Combine like terms: nxI + -1nxI = 0
-36nI + 1nxI = 0

Factor out the Greatest Common Factor (GCF), 'nI'.
nI(-36 + x) = 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.
