Solution for logx+log(x-18)=log(18x) equation:


Simplifying
logx + log(x + -18) = log(18x)

Reorder the terms:
glox + glo(-18 + x) = log(18x)
glox + (-18 * glo + x * glo) = log(18x)
glox + (-18glo + glox) = log(18x)

Reorder the terms:
-18glo + glox + glox = log(18x)

Combine like terms: glox + glox = 2glox
-18glo + 2glox = log(18x)

Remove parenthesis around (18x)
-18glo + 2glox = glo * 18x

Reorder the terms for easier multiplication:
-18glo + 2glox = 18glo * x

Multiply glo * x
-18glo + 2glox = 18glox

Solving
-18glo + 2glox = 18glox

Solving for variable 'g'.

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

Add '-18glox' to each side of the equation.
-18glo + 2glox + -18glox = 18glox + -18glox

Combine like terms: 2glox + -18glox = -16glox
-18glo + -16glox = 18glox + -18glox

Combine like terms: 18glox + -18glox = 0
-18glo + -16glox = 0

Factor out the Greatest Common Factor (GCF), '-2glo'.
-2glo(9 + 8x) = 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 '(9 + 8x)' equal to zero and attempt to solve: Simplifying 9 + 8x = 0 Solving 9 + 8x = 0 Move all terms containing g to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 8x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 8x = 0 + -9 8x = 0 + -9 Combine like terms: 0 + -9 = -9 8x = -9 Add '-8x' to each side of the equation. 8x + -8x = -9 + -8x Combine like terms: 8x + -8x = 0 0 = -9 + -8x Simplifying 0 = -9 + -8x 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.
