Solution for log(-5x)=log(4x-9) equation:


Simplifying
log(-5x) = log(4x + -9)

Remove parenthesis around (-5x)
glo * -5x = log(4x + -9)

Reorder the terms for easier multiplication:
-5glo * x = log(4x + -9)

Multiply glo * x
-5glox = log(4x + -9)

Reorder the terms:
-5glox = glo(-9 + 4x)
-5glox = (-9 * glo + 4x * glo)
-5glox = (-9glo + 4glox)

Solving
-5glox = -9glo + 4glox

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.
9glo + -5glox = -9glo + 9glo + 4glox

Combine like terms: -9glo + 9glo = 0
9glo + -5glox = 0 + 4glox
9glo + -5glox = 4glox

Add '-4glox' to each side of the equation.
9glo + -5glox + -4glox = 4glox + -4glox

Combine like terms: -5glox + -4glox = -9glox
9glo + -9glox = 4glox + -4glox

Combine like terms: 4glox + -4glox = 0
9glo + -9glox = 0

Factor out the Greatest Common Factor (GCF), '9glo'.
9glo(1 + -1x) = 0

Ignore the factor 9.

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