Solution for Log[4](x+5)=log[4](3x-5) equation:


Simplifying
Log[4](x + 5) = log[4](3x + -5)

Reorder the terms:
goL * 4(5 + x) = log[4](3x + -5)

Reorder the terms for easier multiplication:
4goL(5 + x) = log[4](3x + -5)
(5 * 4goL + x * 4goL) = log[4](3x + -5)
(20goL + 4goxL) = log[4](3x + -5)

Reorder the terms:
20goL + 4goxL = glo * 4(-5 + 3x)

Reorder the terms for easier multiplication:
20goL + 4goxL = 4glo(-5 + 3x)
20goL + 4goxL = (-5 * 4glo + 3x * 4glo)
20goL + 4goxL = (-20glo + 12glox)

Solving
20goL + 4goxL = -20glo + 12glox

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.
20goL + 20glo + 4goxL = -20glo + 20glo + 12glox

Reorder the terms:
20glo + 20goL + 4goxL = -20glo + 20glo + 12glox

Combine like terms: -20glo + 20glo = 0
20glo + 20goL + 4goxL = 0 + 12glox
20glo + 20goL + 4goxL = 12glox

Add '-12glox' to each side of the equation.
20glo + 20goL + -12glox + 4goxL = 12glox + -12glox

Reorder the terms:
20glo + -12glox + 20goL + 4goxL = 12glox + -12glox

Combine like terms: 12glox + -12glox = 0
20glo + -12glox + 20goL + 4goxL = 0

Factor out the Greatest Common Factor (GCF), '4go'.
4go(5l + -3lx + 5L + xL) = 0

Ignore the factor 4.

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 '(5l + -3lx + 5L + xL)' equal to zero and attempt to solve: Simplifying 5l + -3lx + 5L + xL = 0 Reorder the terms: 5L + 5l + -3lx + xL = 0 Solving 5L + 5l + -3lx + xL = 0 Move all terms containing g to the left, all other terms to the right. Add '-5L' to each side of the equation. 5L + 5l + -3lx + -5L + xL = 0 + -5L Reorder the terms: 5L + -5L + 5l + -3lx + xL = 0 + -5L Combine like terms: 5L + -5L = 0 0 + 5l + -3lx + xL = 0 + -5L 5l + -3lx + xL = 0 + -5L Remove the zero: 5l + -3lx + xL = -5L Add '-5l' to each side of the equation. 5l + -3lx + -5l + xL = -5L + -5l Reorder the terms: 5l + -5l + -3lx + xL = -5L + -5l Combine like terms: 5l + -5l = 0 0 + -3lx + xL = -5L + -5l -3lx + xL = -5L + -5l Add '3lx' to each side of the equation. -3lx + 3lx + xL = -5L + -5l + 3lx Combine like terms: -3lx + 3lx = 0 0 + xL = -5L + -5l + 3lx xL = -5L + -5l + 3lx Add '-1xL' to each side of the equation. xL + -1xL = -5L + -5l + 3lx + -1xL Combine like terms: xL + -1xL = 0 0 = -5L + -5l + 3lx + -1xL Simplifying 0 = -5L + -5l + 3lx + -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.
