Solution for logx+log(x-13)=log(20x) equation:


Simplifying
logx + log(x + -13) = log(20x)

Reorder the terms:
glox + glo(-13 + x) = log(20x)
glox + (-13 * glo + x * glo) = log(20x)
glox + (-13glo + glox) = log(20x)

Reorder the terms:
-13glo + glox + glox = log(20x)

Combine like terms: glox + glox = 2glox
-13glo + 2glox = log(20x)

Remove parenthesis around (20x)
-13glo + 2glox = glo * 20x

Reorder the terms for easier multiplication:
-13glo + 2glox = 20glo * x

Multiply glo * x
-13glo + 2glox = 20glox

Solving
-13glo + 2glox = 20glox

Solving for variable 'g'.

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

Add '-20glox' to each side of the equation.
-13glo + 2glox + -20glox = 20glox + -20glox

Combine like terms: 2glox + -20glox = -18glox
-13glo + -18glox = 20glox + -20glox

Combine like terms: 20glox + -20glox = 0
-13glo + -18glox = 0

Factor out the Greatest Common Factor (GCF), '-1glo'.
-1glo(13 + 18x) = 0

Ignore the factor -1.

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 '(13 + 18x)' equal to zero and attempt to solve: Simplifying 13 + 18x = 0 Solving 13 + 18x = 0 Move all terms containing g to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + 18x = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 18x = 0 + -13 18x = 0 + -13 Combine like terms: 0 + -13 = -13 18x = -13 Add '-18x' to each side of the equation. 18x + -18x = -13 + -18x Combine like terms: 18x + -18x = 0 0 = -13 + -18x Simplifying 0 = -13 + -18x 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.
