Solution for log(5x-4)=log(x+1)+log(4) equation:


Simplifying
log(5x + -4) = log(x + 1) + log(4)

Reorder the terms:
glo(-4 + 5x) = log(x + 1) + log(4)
(-4 * glo + 5x * glo) = log(x + 1) + log(4)
(-4glo + 5glox) = log(x + 1) + log(4)

Reorder the terms:
-4glo + 5glox = glo(1 + x) + log(4)
-4glo + 5glox = (1 * glo + x * glo) + log(4)
-4glo + 5glox = (1glo + glox) + log(4)

Reorder the terms for easier multiplication:
-4glo + 5glox = 1glo + glox + 4glo

Reorder the terms:
-4glo + 5glox = 1glo + 4glo + glox

Combine like terms: 1glo + 4glo = 5glo
-4glo + 5glox = 5glo + glox

Solving
-4glo + 5glox = 5glo + glox

Solving for variable 'g'.

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

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

Combine like terms: -4glo + -5glo = -9glo
-9glo + 5glox = 5glo + -5glo + glox

Combine like terms: 5glo + -5glo = 0
-9glo + 5glox = 0 + glox
-9glo + 5glox = glox

Add '-1glox' to each side of the equation.
-9glo + 5glox + -1glox = glox + -1glox

Combine like terms: 5glox + -1glox = 4glox
-9glo + 4glox = glox + -1glox

Combine like terms: glox + -1glox = 0
-9glo + 4glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-9 + 4x) = 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 '(-9 + 4x)' equal to zero and attempt to solve: Simplifying -9 + 4x = 0 Solving -9 + 4x = 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 + 4x = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 4x = 0 + 9 4x = 0 + 9 Combine like terms: 0 + 9 = 9 4x = 9 Add '-4x' to each side of the equation. 4x + -4x = 9 + -4x Combine like terms: 4x + -4x = 0 0 = 9 + -4x Simplifying 0 = 9 + -4x 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.
