Solution for log(3x)=log(4)+log(x-1) equation:


Simplifying
log(3x) = log(4) + log(x + -1)

Remove parenthesis around (3x)
glo * 3x = log(4) + log(x + -1)

Reorder the terms for easier multiplication:
3glo * x = log(4) + log(x + -1)

Multiply glo * x
3glox = log(4) + log(x + -1)

Reorder the terms for easier multiplication:
3glox = 4glo + log(x + -1)

Reorder the terms:
3glox = 4glo + glo(-1 + x)
3glox = 4glo + (-1 * glo + x * glo)
3glox = 4glo + (-1glo + glox)

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

Solving
3glox = 3glo + glox

Solving for variable 'g'.

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

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

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

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

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

Combine like terms: glox + -1glox = 0
-3glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-3 + 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 '(-3 + 2x)' equal to zero and attempt to solve: Simplifying -3 + 2x = 0 Solving -3 + 2x = 0 Move all terms containing g to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 2x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2x = 0 + 3 2x = 0 + 3 Combine like terms: 0 + 3 = 3 2x = 3 Add '-2x' to each side of the equation. 2x + -2x = 3 + -2x Combine like terms: 2x + -2x = 0 0 = 3 + -2x Simplifying 0 = 3 + -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.
