Solution for ln(y-1)=ln(x+3) equation:


Simplifying
ln(y + -1) = ln(x + 3)

Reorder the terms:
ln(-1 + y) = ln(x + 3)
(-1 * ln + y * ln) = ln(x + 3)
(-1ln + lny) = ln(x + 3)

Reorder the terms:
-1ln + lny = ln(3 + x)
-1ln + lny = (3 * ln + x * ln)
-1ln + lny = (3ln + lnx)

Solving
-1ln + lny = 3ln + lnx

Solving for variable 'l'.

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

Add '-3ln' to each side of the equation.
-1ln + -3ln + lny = 3ln + -3ln + lnx

Combine like terms: -1ln + -3ln = -4ln
-4ln + lny = 3ln + -3ln + lnx

Combine like terms: 3ln + -3ln = 0
-4ln + lny = 0 + lnx
-4ln + lny = lnx

Add '-1lnx' to each side of the equation.
-4ln + -1lnx + lny = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-4ln + -1lnx + lny = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-4 + -1x + y) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 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 '(-4 + -1x + y)' equal to zero and attempt to solve: Simplifying -4 + -1x + y = 0 Solving -4 + -1x + y = 0 Move all terms containing l to the left, all other terms to the right. Add '4' to each side of the equation. -4 + -1x + 4 + y = 0 + 4 Reorder the terms: -4 + 4 + -1x + y = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1x + y = 0 + 4 -1x + y = 0 + 4 Combine like terms: 0 + 4 = 4 -1x + y = 4 Add 'x' to each side of the equation. -1x + x + y = 4 + x Combine like terms: -1x + x = 0 0 + y = 4 + x y = 4 + x Add '-1y' to each side of the equation. y + -1y = 4 + x + -1y Combine like terms: y + -1y = 0 0 = 4 + x + -1y Simplifying 0 = 4 + x + -1y 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.
