Solution for log(x-9)=-log(x+1) equation:


Simplifying
log(x + -9) = -1log(x + 1)

Reorder the terms:
glo(-9 + x) = -1log(x + 1)
(-9 * glo + x * glo) = -1log(x + 1)
(-9glo + glox) = -1log(x + 1)

Reorder the terms:
-9glo + glox = -1glo(1 + x)
-9glo + glox = (1 * -1glo + x * -1glo)
-9glo + glox = (-1glo + -1glox)

Solving
-9glo + glox = -1glo + -1glox

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.
-9glo + glo + glox = -1glo + glo + -1glox

Combine like terms: -9glo + glo = -8glo
-8glo + glox = -1glo + glo + -1glox

Combine like terms: -1glo + glo = 0
-8glo + glox = 0 + -1glox
-8glo + glox = -1glox

Add 'glox' to each side of the equation.
-8glo + glox + glox = -1glox + glox

Combine like terms: glox + glox = 2glox
-8glo + 2glox = -1glox + glox

Combine like terms: -1glox + glox = 0
-8glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), '2glo'.
2glo(-4 + 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 '(-4 + x)' equal to zero and attempt to solve: Simplifying -4 + x = 0 Solving -4 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + x = 0 + 4 x = 0 + 4 Combine like terms: 0 + 4 = 4 x = 4 Add '-1x' to each side of the equation. x + -1x = 4 + -1x Combine like terms: x + -1x = 0 0 = 4 + -1x Simplifying 0 = 4 + -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.
