Solution for 2log(x-2)=log(x-25) equation:


Simplifying
2log(x + -2) = log(x + -25)

Reorder the terms:
2glo(-2 + x) = log(x + -25)
(-2 * 2glo + x * 2glo) = log(x + -25)
(-4glo + 2glox) = log(x + -25)

Reorder the terms:
-4glo + 2glox = glo(-25 + x)
-4glo + 2glox = (-25 * glo + x * glo)
-4glo + 2glox = (-25glo + glox)

Solving
-4glo + 2glox = -25glo + glox

Solving for variable 'g'.

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

Add '25glo' to each side of the equation.
-4glo + 25glo + 2glox = -25glo + 25glo + glox

Combine like terms: -4glo + 25glo = 21glo
21glo + 2glox = -25glo + 25glo + glox

Combine like terms: -25glo + 25glo = 0
21glo + 2glox = 0 + glox
21glo + 2glox = glox

Add '-1glox' to each side of the equation.
21glo + 2glox + -1glox = glox + -1glox

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

Combine like terms: glox + -1glox = 0
21glo + 1glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(21 + x) = 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 + x)' equal to zero and attempt to solve: Simplifying 21 + x = 0 Solving 21 + x = 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 + x = 0 + -21 Combine like terms: 21 + -21 = 0 0 + x = 0 + -21 x = 0 + -21 Combine like terms: 0 + -21 = -21 x = -21 Add '-1x' to each side of the equation. x + -1x = -21 + -1x Combine like terms: x + -1x = 0 0 = -21 + -1x Simplifying 0 = -21 + -1x 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.
