Solution for 2log(x+1)=log(3x+7) equation:


Simplifying
2log(x + 1) = log(3x + 7)

Reorder the terms:
2glo(1 + x) = log(3x + 7)
(1 * 2glo + x * 2glo) = log(3x + 7)
(2glo + 2glox) = log(3x + 7)

Reorder the terms:
2glo + 2glox = glo(7 + 3x)
2glo + 2glox = (7 * glo + 3x * glo)
2glo + 2glox = (7glo + 3glox)

Solving
2glo + 2glox = 7glo + 3glox

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.
2glo + -7glo + 2glox = 7glo + -7glo + 3glox

Combine like terms: 2glo + -7glo = -5glo
-5glo + 2glox = 7glo + -7glo + 3glox

Combine like terms: 7glo + -7glo = 0
-5glo + 2glox = 0 + 3glox
-5glo + 2glox = 3glox

Add '-3glox' to each side of the equation.
-5glo + 2glox + -3glox = 3glox + -3glox

Combine like terms: 2glox + -3glox = -1glox
-5glo + -1glox = 3glox + -3glox

Combine like terms: 3glox + -3glox = 0
-5glo + -1glox = 0

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

Ignore the factor -1.

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