Solution for log(-2x-6)=log(x+9) equation:


Simplifying
log(-2x + -6) = log(x + 9)

Reorder the terms:
glo(-6 + -2x) = log(x + 9)
(-6 * glo + -2x * glo) = log(x + 9)
(-6glo + -2glox) = log(x + 9)

Reorder the terms:
-6glo + -2glox = glo(9 + x)
-6glo + -2glox = (9 * glo + x * glo)
-6glo + -2glox = (9glo + glox)

Solving
-6glo + -2glox = 9glo + glox

Solving for variable 'g'.

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

Add '-9glo' to each side of the equation.
-6glo + -9glo + -2glox = 9glo + -9glo + glox

Combine like terms: -6glo + -9glo = -15glo
-15glo + -2glox = 9glo + -9glo + glox

Combine like terms: 9glo + -9glo = 0
-15glo + -2glox = 0 + glox
-15glo + -2glox = glox

Add '-1glox' to each side of the equation.
-15glo + -2glox + -1glox = glox + -1glox

Combine like terms: -2glox + -1glox = -3glox
-15glo + -3glox = glox + -1glox

Combine like terms: glox + -1glox = 0
-15glo + -3glox = 0

Factor out the Greatest Common Factor (GCF), '-3glo'.
-3glo(5 + x) = 0

Ignore the factor -3.

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 '(5 + x)' equal to zero and attempt to solve: Simplifying 5 + x = 0 Solving 5 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Add '-1x' to each side of the equation. x + -1x = -5 + -1x Combine like terms: x + -1x = 0 0 = -5 + -1x Simplifying 0 = -5 + -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.
