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


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

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

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

Solving
1glo + 7glox = -2glo + glox

Solving for variable 'g'.

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

Add '2glo' to each side of the equation.
1glo + 2glo + 7glox = -2glo + 2glo + glox

Combine like terms: 1glo + 2glo = 3glo
3glo + 7glox = -2glo + 2glo + glox

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

Add '-1glox' to each side of the equation.
3glo + 7glox + -1glox = glox + -1glox

Combine like terms: 7glox + -1glox = 6glox
3glo + 6glox = glox + -1glox

Combine like terms: glox + -1glox = 0
3glo + 6glox = 0

Factor out the Greatest Common Factor (GCF), '3glo'.
3glo(1 + 2x) = 0

Ignore the factor 3.

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