Solution for 2log(x+2)=log(x+8) equation:


Simplifying
2log(x + 2) = log(x + 8)

Reorder the terms:
2glo(2 + x) = log(x + 8)
(2 * 2glo + x * 2glo) = log(x + 8)
(4glo + 2glox) = log(x + 8)

Reorder the terms:
4glo + 2glox = glo(8 + x)
4glo + 2glox = (8 * glo + x * glo)
4glo + 2glox = (8glo + glox)

Solving
4glo + 2glox = 8glo + glox

Solving for variable 'g'.

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

Add '-8glo' to each side of the equation.
4glo + -8glo + 2glox = 8glo + -8glo + glox

Combine like terms: 4glo + -8glo = -4glo
-4glo + 2glox = 8glo + -8glo + glox

Combine like terms: 8glo + -8glo = 0
-4glo + 2glox = 0 + glox
-4glo + 2glox = glox

Add '-1glox' to each side of the equation.
-4glo + 2glox + -1glox = glox + -1glox

Combine like terms: 2glox + -1glox = 1glox
-4glo + 1glox = glox + -1glox

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

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-4 + 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 '(-4 + x)' equal to zero and attempt to solve: Simplifying -4 + x = 0 Solving -4 + x = 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 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + x = 0 + 4 x = 0 + 4 Combine like terms: 0 + 4 = 4 x = 4 Add '-1x' to each side of the equation. x + -1x = 4 + -1x Combine like terms: x + -1x = 0 0 = 4 + -1x Simplifying 0 = 4 + -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.
