Solution for logx+log(x-1)=log(3x+12) equation:


Simplifying
logx + log(x + -1) = log(3x + 12)

Reorder the terms:
glox + glo(-1 + x) = log(3x + 12)
glox + (-1 * glo + x * glo) = log(3x + 12)
glox + (-1glo + glox) = log(3x + 12)

Reorder the terms:
-1glo + glox + glox = log(3x + 12)

Combine like terms: glox + glox = 2glox
-1glo + 2glox = log(3x + 12)

Reorder the terms:
-1glo + 2glox = glo(12 + 3x)
-1glo + 2glox = (12 * glo + 3x * glo)
-1glo + 2glox = (12glo + 3glox)

Solving
-1glo + 2glox = 12glo + 3glox

Solving for variable 'g'.

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

Add '-12glo' to each side of the equation.
-1glo + -12glo + 2glox = 12glo + -12glo + 3glox

Combine like terms: -1glo + -12glo = -13glo
-13glo + 2glox = 12glo + -12glo + 3glox

Combine like terms: 12glo + -12glo = 0
-13glo + 2glox = 0 + 3glox
-13glo + 2glox = 3glox

Add '-3glox' to each side of the equation.
-13glo + 2glox + -3glox = 3glox + -3glox

Combine like terms: 2glox + -3glox = -1glox
-13glo + -1glox = 3glox + -3glox

Combine like terms: 3glox + -3glox = 0
-13glo + -1glox = 0

Factor out the Greatest Common Factor (GCF), '-1glo'.
-1glo(13 + x) = 0

Ignore the factor -1.

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 '(13 + x)' equal to zero and attempt to solve: Simplifying 13 + x = 0 Solving 13 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = 0 + -13 Combine like terms: 13 + -13 = 0 0 + x = 0 + -13 x = 0 + -13 Combine like terms: 0 + -13 = -13 x = -13 Add '-1x' to each side of the equation. x + -1x = -13 + -1x Combine like terms: x + -1x = 0 0 = -13 + -1x Simplifying 0 = -13 + -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.
