Solution for log(x)+log(x-1)=log(20) equation:


Simplifying
log(x) + log(x + -1) = log(20)

Multiply glo * x
glox + log(x + -1) = log(20)

Reorder the terms:
glox + glo(-1 + x) = log(20)
glox + (-1 * glo + x * glo) = log(20)
glox + (-1glo + glox) = log(20)

Reorder the terms:
-1glo + glox + glox = log(20)

Combine like terms: glox + glox = 2glox
-1glo + 2glox = log(20)

Reorder the terms for easier multiplication:
-1glo + 2glox = 20glo

Solving
-1glo + 2glox = 20glo

Solving for variable 'g'.

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

Add '-20glo' to each side of the equation.
-1glo + -20glo + 2glox = 20glo + -20glo

Combine like terms: -1glo + -20glo = -21glo
-21glo + 2glox = 20glo + -20glo

Combine like terms: 20glo + -20glo = 0
-21glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-21 + 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 '(-21 + 2x)' equal to zero and attempt to solve: Simplifying -21 + 2x = 0 Solving -21 + 2x = 0 Move all terms containing g to the left, all other terms to the right. Add '21' to each side of the equation. -21 + 21 + 2x = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 2x = 0 + 21 2x = 0 + 21 Combine like terms: 0 + 21 = 21 2x = 21 Add '-2x' to each side of the equation. 2x + -2x = 21 + -2x Combine like terms: 2x + -2x = 0 0 = 21 + -2x Simplifying 0 = 21 + -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.
