Solution for logx+log(x-18)=log(3x) equation:


Simplifying
logx + log(x + -18) = log(3x)

Reorder the terms:
glox + glo(-18 + x) = log(3x)
glox + (-18 * glo + x * glo) = log(3x)
glox + (-18glo + glox) = log(3x)

Reorder the terms:
-18glo + glox + glox = log(3x)

Combine like terms: glox + glox = 2glox
-18glo + 2glox = log(3x)

Remove parenthesis around (3x)
-18glo + 2glox = glo * 3x

Reorder the terms for easier multiplication:
-18glo + 2glox = 3glo * x

Multiply glo * x
-18glo + 2glox = 3glox

Solving
-18glo + 2glox = 3glox

Solving for variable 'g'.

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

Add '-3glox' to each side of the equation.
-18glo + 2glox + -3glox = 3glox + -3glox

Combine like terms: 2glox + -3glox = -1glox
-18glo + -1glox = 3glox + -3glox

Combine like terms: 3glox + -3glox = 0
-18glo + -1glox = 0

Factor out the Greatest Common Factor (GCF), '-1glo'.
-1glo(18 + x) = 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 '(18 + x)' equal to zero and attempt to solve: Simplifying 18 + x = 0 Solving 18 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + x = 0 + -18 Combine like terms: 18 + -18 = 0 0 + x = 0 + -18 x = 0 + -18 Combine like terms: 0 + -18 = -18 x = -18 Add '-1x' to each side of the equation. x + -1x = -18 + -1x Combine like terms: x + -1x = 0 0 = -18 + -1x Simplifying 0 = -18 + -1x 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.
