Solution for log(3x)=log(4)+log(x-5) equation:


Simplifying
log(3x) = log(4) + log(x + -5)

Remove parenthesis around (3x)
glo * 3x = log(4) + log(x + -5)

Reorder the terms for easier multiplication:
3glo * x = log(4) + log(x + -5)

Multiply glo * x
3glox = log(4) + log(x + -5)

Reorder the terms for easier multiplication:
3glox = 4glo + log(x + -5)

Reorder the terms:
3glox = 4glo + glo(-5 + x)
3glox = 4glo + (-5 * glo + x * glo)
3glox = 4glo + (-5glo + glox)

Combine like terms: 4glo + -5glo = -1glo
3glox = -1glo + glox

Solving
3glox = -1glo + glox

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.
glo + 3glox = -1glo + glo + glox

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

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

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

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

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(1 + 2x) = 0

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 + 2x)' equal to zero and attempt to solve: Simplifying 1 + 2x = 0 Solving 1 + 2x = 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 + 2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 2x = 0 + -1 2x = 0 + -1 Combine like terms: 0 + -1 = -1 2x = -1 Add '-2x' to each side of the equation. 2x + -2x = -1 + -2x Combine like terms: 2x + -2x = 0 0 = -1 + -2x Simplifying 0 = -1 + -2x 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.
