Solution for log(x+9)=log(2x-7) equation:


Simplifying
log(x + 9) = log(2x + -7)

Reorder the terms:
glo(9 + x) = log(2x + -7)
(9 * glo + x * glo) = log(2x + -7)
(9glo + glox) = log(2x + -7)

Reorder the terms:
9glo + glox = glo(-7 + 2x)
9glo + glox = (-7 * glo + 2x * glo)
9glo + glox = (-7glo + 2glox)

Solving
9glo + glox = -7glo + 2glox

Solving for variable 'g'.

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

Add '7glo' to each side of the equation.
9glo + 7glo + glox = -7glo + 7glo + 2glox

Combine like terms: 9glo + 7glo = 16glo
16glo + glox = -7glo + 7glo + 2glox

Combine like terms: -7glo + 7glo = 0
16glo + glox = 0 + 2glox
16glo + glox = 2glox

Add '-2glox' to each side of the equation.
16glo + glox + -2glox = 2glox + -2glox

Combine like terms: glox + -2glox = -1glox
16glo + -1glox = 2glox + -2glox

Combine like terms: 2glox + -2glox = 0
16glo + -1glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(16 + -1x) = 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.
