Solution for log(2x+1)=log(x-1) equation:


Simplifying
log(2x + 1) = log(x + -1)

Reorder the terms:
glo(1 + 2x) = log(x + -1)
(1 * glo + 2x * glo) = log(x + -1)
(1glo + 2glox) = log(x + -1)

Reorder the terms:
1glo + 2glox = glo(-1 + x)
1glo + 2glox = (-1 * glo + x * glo)
1glo + 2glox = (-1glo + glox)

Solving
1glo + 2glox = -1glo + glox

Solving for variable 'g'.

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

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

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

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

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

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

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

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

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 '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Add '-1x' to each side of the equation. x + -1x = -2 + -1x Combine like terms: x + -1x = 0 0 = -2 + -1x Simplifying 0 = -2 + -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.
