Solution for log(3x+7)=log(8x-13) equation:


Simplifying
log(3x + 7) = log(8x + -13)

Reorder the terms:
glo(7 + 3x) = log(8x + -13)
(7 * glo + 3x * glo) = log(8x + -13)
(7glo + 3glox) = log(8x + -13)

Reorder the terms:
7glo + 3glox = glo(-13 + 8x)
7glo + 3glox = (-13 * glo + 8x * glo)
7glo + 3glox = (-13glo + 8glox)

Solving
7glo + 3glox = -13glo + 8glox

Solving for variable 'g'.

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

Add '13glo' to each side of the equation.
7glo + 13glo + 3glox = -13glo + 13glo + 8glox

Combine like terms: 7glo + 13glo = 20glo
20glo + 3glox = -13glo + 13glo + 8glox

Combine like terms: -13glo + 13glo = 0
20glo + 3glox = 0 + 8glox
20glo + 3glox = 8glox

Add '-8glox' to each side of the equation.
20glo + 3glox + -8glox = 8glox + -8glox

Combine like terms: 3glox + -8glox = -5glox
20glo + -5glox = 8glox + -8glox

Combine like terms: 8glox + -8glox = 0
20glo + -5glox = 0

Factor out the Greatest Common Factor (GCF), '5glo'.
5glo(4 + -1x) = 0

Ignore the factor 5.

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