Solution for log(7)(8x+20)=log(7)(x+6) equation:


Simplifying
log(7)(8x + 20) = log(7)(x + 6)

Reorder the terms:
glo * 7(20 + 8x) = log(7)(x + 6)

Reorder the terms for easier multiplication:
7glo(20 + 8x) = log(7)(x + 6)
(20 * 7glo + 8x * 7glo) = log(7)(x + 6)
(140glo + 56glox) = log(7)(x + 6)

Reorder the terms:
140glo + 56glox = glo * 7(6 + x)

Reorder the terms for easier multiplication:
140glo + 56glox = 7glo(6 + x)
140glo + 56glox = (6 * 7glo + x * 7glo)
140glo + 56glox = (42glo + 7glox)

Solving
140glo + 56glox = 42glo + 7glox

Solving for variable 'g'.

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

Add '-42glo' to each side of the equation.
140glo + -42glo + 56glox = 42glo + -42glo + 7glox

Combine like terms: 140glo + -42glo = 98glo
98glo + 56glox = 42glo + -42glo + 7glox

Combine like terms: 42glo + -42glo = 0
98glo + 56glox = 0 + 7glox
98glo + 56glox = 7glox

Add '-7glox' to each side of the equation.
98glo + 56glox + -7glox = 7glox + -7glox

Combine like terms: 56glox + -7glox = 49glox
98glo + 49glox = 7glox + -7glox

Combine like terms: 7glox + -7glox = 0
98glo + 49glox = 0

Factor out the Greatest Common Factor (GCF), '49glo'.
49glo(2 + x) = 0

Ignore the factor 49.

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.
