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


Simplifying
log(x + -1) = -1log(x + 3)

Reorder the terms:
glo(-1 + x) = -1log(x + 3)
(-1 * glo + x * glo) = -1log(x + 3)
(-1glo + glox) = -1log(x + 3)

Reorder the terms:
-1glo + glox = -1glo(3 + x)
-1glo + glox = (3 * -1glo + x * -1glo)
-1glo + glox = (-3glo + -1glox)

Solving
-1glo + glox = -3glo + -1glox

Solving for variable 'g'.

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

Add '3glo' to each side of the equation.
-1glo + 3glo + glox = -3glo + 3glo + -1glox

Combine like terms: -1glo + 3glo = 2glo
2glo + glox = -3glo + 3glo + -1glox

Combine like terms: -3glo + 3glo = 0
2glo + glox = 0 + -1glox
2glo + glox = -1glox

Add 'glox' to each side of the equation.
2glo + glox + glox = -1glox + glox

Combine like terms: glox + glox = 2glox
2glo + 2glox = -1glox + glox

Combine like terms: -1glox + glox = 0
2glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), '2glo'.
2glo(1 + x) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'glo' equal to zero and attempt to solve: Simplifying glo = 0 Solving glo = 0 Move all terms containing g to the left, all other terms to the right. Simplifying glo = 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 g to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Add '-1x' to each side of the equation. x + -1x = -1 + -1x Combine like terms: x + -1x = 0 0 = -1 + -1x Simplifying 0 = -1 + -1x 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.
