Solution for Ln(5x+4)=ln(3-x) equation:


Simplifying
Ln(5x + 4) = ln(3 + -1x)

Reorder the terms:
nL(4 + 5x) = ln(3 + -1x)
(4 * nL + 5x * nL) = ln(3 + -1x)
(4nL + 5nxL) = ln(3 + -1x)
4nL + 5nxL = (3 * ln + -1x * ln)
4nL + 5nxL = (3ln + -1lnx)

Solving
4nL + 5nxL = 3ln + -1lnx

Solving for variable 'n'.

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

Add '-3ln' to each side of the equation.
4nL + -3ln + 5nxL = 3ln + -3ln + -1lnx

Reorder the terms:
-3ln + 4nL + 5nxL = 3ln + -3ln + -1lnx

Combine like terms: 3ln + -3ln = 0
-3ln + 4nL + 5nxL = 0 + -1lnx
-3ln + 4nL + 5nxL = -1lnx

Add 'lnx' to each side of the equation.
-3ln + 4nL + lnx + 5nxL = -1lnx + lnx

Reorder the terms:
-3ln + lnx + 4nL + 5nxL = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-3ln + lnx + 4nL + 5nxL = 0
