Solution for log(x-4)-log(x)=log(x+2) equation:


Simplifying
log(x + -4) + -1log(x) = log(x + 2)

Reorder the terms:
glo(-4 + x) + -1log(x) = log(x + 2)
(-4 * glo + x * glo) + -1log(x) = log(x + 2)
(-4glo + glox) + -1log(x) = log(x + 2)

Multiply glo * x
-4glo + glox + -1glox = log(x + 2)

Combine like terms: glox + -1glox = 0
-4glo + 0 = log(x + 2)
-4glo = log(x + 2)

Reorder the terms:
-4glo = glo(2 + x)
-4glo = (2 * glo + x * glo)
-4glo = (2glo + glox)

Solving
-4glo = 2glo + glox

Solving for variable 'g'.

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

Add '-2glo' to each side of the equation.
-4glo + -2glo = 2glo + -2glo + glox

Combine like terms: -4glo + -2glo = -6glo
-6glo = 2glo + -2glo + glox

Combine like terms: 2glo + -2glo = 0
-6glo = 0 + glox
-6glo = glox

Add '-1glox' to each side of the equation.
-6glo + -1glox = glox + -1glox

Combine like terms: glox + -1glox = 0
-6glo + -1glox = 0

Factor out the Greatest Common Factor (GCF), '-1glo'.
-1glo(6 + 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 '(6 + x)' equal to zero and attempt to solve: Simplifying 6 + x = 0 Solving 6 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + x = 0 + -6 x = 0 + -6 Combine like terms: 0 + -6 = -6 x = -6 Add '-1x' to each side of the equation. x + -1x = -6 + -1x Combine like terms: x + -1x = 0 0 = -6 + -1x Simplifying 0 = -6 + -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.
