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


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

Multiply goL * x
goxL + log(x + -4) = log(5x)

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

Reorder the terms:
-4glo + glox + goxL = log(5x)

Remove parenthesis around (5x)
-4glo + glox + goxL = glo * 5x

Reorder the terms for easier multiplication:
-4glo + glox + goxL = 5glo * x

Multiply glo * x
-4glo + glox + goxL = 5glox

Solving
-4glo + glox + goxL = 5glox

Solving for variable 'g'.

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

Add '-5glox' to each side of the equation.
-4glo + glox + -5glox + goxL = 5glox + -5glox

Combine like terms: glox + -5glox = -4glox
-4glo + -4glox + goxL = 5glox + -5glox

Combine like terms: 5glox + -5glox = 0
-4glo + -4glox + goxL = 0

Factor out the Greatest Common Factor (GCF), 'go'.
go(-4l + -4lx + xL) = 0

Subproblem 1

Set the factor 'go' equal to zero and attempt to solve: Simplifying go = 0 Solving go = 0 Move all terms containing g to the left, all other terms to the right. Simplifying go = 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 '(-4l + -4lx + xL)' equal to zero and attempt to solve: Simplifying -4l + -4lx + xL = 0 Solving -4l + -4lx + xL = 0 Move all terms containing g to the left, all other terms to the right. Add '4l' to each side of the equation. -4l + -4lx + 4l + xL = 0 + 4l Reorder the terms: -4l + 4l + -4lx + xL = 0 + 4l Combine like terms: -4l + 4l = 0 0 + -4lx + xL = 0 + 4l -4lx + xL = 0 + 4l Remove the zero: -4lx + xL = 4l Add '4lx' to each side of the equation. -4lx + 4lx + xL = 4l + 4lx Combine like terms: -4lx + 4lx = 0 0 + xL = 4l + 4lx xL = 4l + 4lx Add '-1xL' to each side of the equation. xL + -1xL = 4l + 4lx + -1xL Combine like terms: xL + -1xL = 0 0 = 4l + 4lx + -1xL Simplifying 0 = 4l + 4lx + -1xL 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.
