Solution for log[2](4x+7)=log[2](3x+9) equation:


Simplifying
log[2](4x + 7) = log[2](3x + 9)

Reorder the terms:
glo * 2(7 + 4x) = log[2](3x + 9)

Reorder the terms for easier multiplication:
2glo(7 + 4x) = log[2](3x + 9)
(7 * 2glo + 4x * 2glo) = log[2](3x + 9)
(14glo + 8glox) = log[2](3x + 9)

Reorder the terms:
14glo + 8glox = glo * 2(9 + 3x)

Reorder the terms for easier multiplication:
14glo + 8glox = 2glo(9 + 3x)
14glo + 8glox = (9 * 2glo + 3x * 2glo)
14glo + 8glox = (18glo + 6glox)

Solving
14glo + 8glox = 18glo + 6glox

Solving for variable 'g'.

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

Add '-18glo' to each side of the equation.
14glo + -18glo + 8glox = 18glo + -18glo + 6glox

Combine like terms: 14glo + -18glo = -4glo
-4glo + 8glox = 18glo + -18glo + 6glox

Combine like terms: 18glo + -18glo = 0
-4glo + 8glox = 0 + 6glox
-4glo + 8glox = 6glox

Add '-6glox' to each side of the equation.
-4glo + 8glox + -6glox = 6glox + -6glox

Combine like terms: 8glox + -6glox = 2glox
-4glo + 2glox = 6glox + -6glox

Combine like terms: 6glox + -6glox = 0
-4glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), '2glo'.
2glo(-2 + x) = 0

Ignore the factor 2.

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 '(-2 + x)' equal to zero and attempt to solve: Simplifying -2 + x = 0 Solving -2 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + x = 0 + 2 x = 0 + 2 Combine like terms: 0 + 2 = 2 x = 2 Add '-1x' to each side of the equation. x + -1x = 2 + -1x Combine like terms: x + -1x = 0 0 = 2 + -1x Simplifying 0 = 2 + -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.
